Editing Vehicle identification number (section)

===Worked example===
Consider the hypothetical VIN {{mono|1M8GDM9A_KP042788}}, where the underscore will be the check digit.

# The VIN's value is calculated from the above transliteration table. This number is used in the rest of the calculation.
# Copy the ''weights'' from the weight factor row above.
# The ''products'' row is the result of the multiplication of the columns in the ''Value'' and ''Weight'' rows.
# The products (8, 28, 48, 35 ... 24, 16) are all added together to yield a sum, ''351''.
# Find the remainder after dividing by 11{{ubl
|1= 351 [[modulo operation|MOD]] 11 = 10
|2= 351 ÷ 11 = 31{{frac|'''10'''|11}}
}}
# The remainder is the check digit. If the remainder is 10, the check digit is X. In this example, the remainder is 10, so the check digit is transliterated as ''X''.

With a check digit of ''X'', the VIN {{mono|1M8GDM9A_KP042788}} is written {{mono|1M8GDM9A''X''KP042788}}.

A VIN with ''straight-ones'' (seventeen consecutive ''1''s) has the nice feature that its check digit ''1'' matches the calculated value ''1''. This is because a value of one multiplied by 89 (sum of weights) is 89, and 89 divided by 11 is 8 with remainder {{frac|1|11}}; thus 1 is the check digit. This is a way to test a VIN-check algorithm.
