''Chemical Abstracts'' (''CA'') began as a volunteer effort and developed from there. The use of volunteer abstractors was phased out in 1994. ''Chemical Abstracts'' has been associated with the American Chemical Society in one way or another since 1907.<ref>{{Cite web |author=American Chemistry Society.

For many years, beginning in 1909, the offices of ''Chemical Abstracts'' were housed in various places on the Columbus, Ohio campus of [[Ohio State University]]<!--Wikipedians do not use "The" as part of Ohio State's name; it is considered a marketing gimmick, and routinely deleted.-->, including McPherson Laboratory and [[Watts Hall]].<ref>Chemical Abstracts Service.

Accessed 8.1.2009</ref> In 1965, CAS moved to a new {{convert|50|acre|m2|adj=on}} site on the west bank of the [[Olentangy River]], just north of The Ohio State campus. This campus became well known in the Columbus area and famous as the site of many [[Columbus Symphony Orchestra]] pop concerts. In 2009, the campus consisted of three buildings.

In 1907, [[William A. Noyes]] had enlarged the ''Review of American Chemical Research'', an abstracting publication begun by [[Arthur Amos Noyes|Arthur Noyes]] in 1895 that was the forerunner of ''Chemical Abstracts''. When it became evident that a separate publication containing these abstracts was needed, Noyes became the first editor of the new publication, ''Chemical Abstracts''.

[[Evan J. Crane|E. J. Crane]] became the first Director of Chemical Abstracts Service when it became an American Chemical Society division in 1956. Crane had been ''CA'' editor since 1915, and his dedication was a key factor in its long-term success.

Dale B. Baker became the CAS Director upon Crane's retirement in 1958. According to CAS, his visionary view of CAS' potential "led to expansion, modernization, and the forging of international alliances with other information organizations."<ref>Chemical Abstracts Service.

The CAS Chemical Registry System was introduced in 1965. CAS developed a unique registry number to identify chemical substances. Agencies such as the [[United States Environmental Protection Agency|U.S. Environmental Protection Agency]] and local fire departments around the world now rely on these numbers for the definite identification of substances. According to the ACS, this is the largest chemical substance database in the world.

In 1965, CAS left their offices at OSU for a new headquarters north of campus. Ground was broken in 1971 for an expansion to the building designed by architects [[Brubaker/Brandt]] to accommodate the review of 400,000 new research reports printed each year. The 5-story 142,000 square foot building opened in May 1973.<ref>{{Cite web |date=May 27, 1973 |title=CA to Dedicate New Office Building |url=https://login.webproxy3.columbuslibrary.org/login?qurl=https://infoweb.newsbank.com%2fapps%2fnews%2fdocument-view%3fp%3dWORLDNEWS%26t%3dfavorite%3aCOLUMBUS%21Columbus%2520Dispatch%2520Historical%2520and%2520Current%26sort%3dYMD_date%3aD%26page%3d10%26fld-base-0%3dalltext%26maxresults%3d20%26val-base-0%3d%2522Brubaker-Brandt%2522%26docref%3dimage%2fv2%3a1467499E363272B3%40EANX-NB-1627317252357A4E%402441830-16272F64F2E2C661%4040-16272F64F2E2C661%40 |access-date=2022-08-02 |website=The Columbus Dispatch}}</ref>

In 2007, the ACS designated its Chemical Abstracts Service subdivision an [[National Historic Chemical Landmarks|ACS National Historic Chemical Landmark]] in recognition of its significance as a comprehensive repository of research in chemistry and related sciences.<ref>[http://portal.acs.org/portal/PublicWebSite/education/whatischemistry/landmarks/cas/index.htm Chemical Abstracts Service (CAS)] {{Webarchive|url=https://archive.today/20120712080702/http://portal.acs.org/portal/PublicWebSite/education/whatischemistry/landmarks/cas/index.htm |date=2012-07-12 }}, American Chemical Society.</ref>

In 2021, CAS rebranded along with a change in logo. The organization updated their mission to be more focused on dynamic responsiveness due to ongoing changes within scientific industries and communities.<ref>{{Cite web|date=2021-04-28|title=CAS launches new brand reflecting strategic evolution to empower smarter science|url=https://www.cas.org/resources/press-releases/cas-new-brand}}</ref>

In 2022, CAS announced the release of almost half a million CAS registry numbers under an open license in their Common Chemistry project.<ref>{{cite web |url=https://commonchemistry.cas.org/ |title=CAS Common Chemistry |author=American Chemical Society |date=2023 |access-date=12 February 2023}}</ref><ref>{{cite journal |last1=Jacobs |first1=Andrea |last2=Williams |first2=Dustin |last3=Hickey |first3=Katherine |last4=Patrick |first4=Nathan |last5=Williams |first5=Antony J. |last6=Chalk |first6=Stuart |last7=McEwen |first7=Leah |last8=Willighagen |first8=Egon |last9=Walker |first9=Martin |last10=Bolton |first10=Evan |last11=Sinclair |first11=Gabriel |last12=Sanford |first12=Adam |title=CAS Common Chemistry in 2021: Expanding Access to Trusted Chemical Information for the Scientific Community |journal=Journal of Chemical Information and Modeling |date=13 June 2022 |volume=62 |issue=11 |pages=2737–2743 |doi=10.1021/acs.jcim.2c00268 |pmid=35559614 |pmc=9199008 }}</ref>
