Calculation method of ID card check code

1. Multiply the digits of the previous ID number 17 by different coefficients respectively. The coefficients from the first place to the seventeenth place are: 7-9-10-5-8-4-2-1-6-3-7-9-10-5-8-4-2.

2. Add the multiplication results of this 17 digit and the coefficient.

3. Divide the added sum by 1 1 to get the remainder.

4. The remainder can only be11-2-3-4-5-6-7-8-9-10. The number corresponding to the last ID card is 1-0-X-9-8-7-6-5-4-3-2. (that is, the remainder 0 corresponds to 1, the remainder 1 corresponds to 0, and the remainder 2 corresponds to x ...)
