VIN Check Digit is calculated by applying a formula to the other 16 digits of the VIN. If the calculated value and the value you have entered do not match then there is a mistake in the VIN (or the calculation). However, a match does not prove the VIN is correct, because there is still a 1 in 11 chance of any two distinct VINs having a matching check digit. See here for more information on VINs and their check digits.
