Vehicle Identification Number (VIN)

-----------------------------------

内容太多,就解释其中两条比较重要的,一个年份,一个是检查VIN的内容是否真实,相当于奇偶校验位.

Check Digit

1) The following algorithm is used for calculating check digits:

Each letter is assigned a numeric value. character A B C D E F G H I

value 1 2 3 4 5 6 7 8 9

character J K L M N O P Q R

value 1 2 3 4 5 6 7 8 9

character S T U V W X Y Z

value 2 3 4 5 6 7 8 9

2) Each number or character value is multiplied by the factor for that position.

position 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

factor 8 7 6 5 4 3 2 10 0 9 8 7 6 5 4 3 2

3) The resulting products are summed.

4) The total is divided by 11.

5) The check digit is the remainder. If the remainder is 10 then the check digit is X (Roman numeral 10).

The only place where the letter "O" has been observed is in the WMI. Other letters that do not normally appear are the letters "I" and "Q" (because of the possibility of confusing them with the numbers "1" and "0").
