[SQL Server] math_function DL : 0: 身份证前17位是本体码，最后一位是校验码，它的生成过程如下：一、对前17位数字本体码加权求和：S=sum(Ai * Wi),其中Ai表示第i位置上的身份证号码数字值，Wi表示第i位置上的加权因子，依次为7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2。二、计算模 Y = MOD(S, 11)。三、通过模得到对应的校验码，Y = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10，分别对应着校验码1, 0, X, 9, 8, 7, 6, 5, 4, 3, 2。-ID card 17 is the body code, the last one is the check code, it generates the process is as follows: I, on the first 17-digit code body weighted sum: S = sum (Ai* Wi), where Ai represents the first i positions of the identity card number numeric value, Wi said that the first i positions of the weighting factor, followed by 7 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2. Second, computing mode Y = MOD (S, 11). Third, through the mold by the corresponding check code, Y = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, corresponding to the check code 1, 0, X, 9, 8 , 7, 6, 5, 4, 3, 2.
