What are the last four digits of Mashan girl's ID card?

The last four digits of the ID card indicate the sequence code and the check code.

The State Council stipulates that starting from 1999 10+00, a national ID number system will be established and implemented.

Citizen ID number is compiled according to the national standard GB11643-1999 "Citizen ID Number" and consists of 18 digits:

The first six digits are administrative division codes, which refer to the administrative regions where citizens' permanent residence is located when they first apply for resident identity cards.

The 7th to14th digits are the birth date code.

The numbers 15 to 17 are sequence codes, which are allocated to everyone in a unified and reasonable way according to the population and in a fixed order. The last digit is allocated to odd-numbered men and even-numbered women.

18 bits are check codes. The purpose is to check the correctness of the ID number, which is randomly generated by the computer, so it is no longer singular for men or even women.

Check code (bit 18)

Weighted summation formula of (1) 17-bit digital ontology code

S = Sum(Ai * Wi), i = 0, ..., 16, first add the weights of the first 17 bits.

Ai: the numerical value of the ID number indicating the position of I.

Wi: indicates the weighting coefficient of the ith position.

wi:7 9 10 5 8 4 2 1 6 3 7 9 10 5 8 4 2

(2) Calculation module

Y = mod(S， 1 1)

(3) Obtaining the corresponding check code through the module.

Y: 0 1 2 3 4 5 6 7 8 9 10

Check code: 10x9882
