When trying to validate a VIN with a check digit, first either (a) remove the check digit for the purpose of calculation or (b) use a weight of zero (see below) to cancel it out. The original value of the check digit is then compared with the calculated value. If the calculated value is 0–9, the check digit must match the calculated value.
For instance, the UPC-A barcode for a box of tissues is "036000241457". The last digit is the check digit "7", and if the other numbers are correct then the check digit calculation must produce 7. Add the odd number digits: 0+6+0+2+1+5 = 14. Multiply the result by 3: 14 × 3 = 42. Add the even number digits: 3+0+0+4+4 = 11.
Luhn algorithm. The Luhn algorithm or Luhn formula, also known as the " modulus 10" or "mod 10" algorithm, named after its creator, IBM scientist Hans Peter Luhn, is a simple check digit formula used to validate a variety of identification numbers. It is described in US patent 2950048A, granted on 23 August 1960. [ 1]

Here is how to do the checksum calculation: Take the value (0 through 42) of each character in the barcode excluding start and stop codes. Sum the values. Divide the result by 10 (for Mod 10 check digit) or by 43 (for Mod 43 check digit). The remainder is the value of the checksum character to be appended.
The check digit is calculated from digits 1–11 using the Luhn algorithm. It is derived from the sum of the numbers that arise when the digits are alternately multiplied by 2 and 1; the difference of this sum from the next multiple of ten produces the check digit [ 4 ] (for examples of this see wagon numbers ).
