/** | |
* 身份证号码验证 | |
* 1、号码的结构 | |
* 公民身份号码是特征组合码,由十七位数字本体码和一位校验码组成。排列顺序从左至右依次为:六位数字地址码, | |
* 八位数字出生日期码,三位数字顺序码和一位数字校验码。 | |
* 2、地址码(前六位数) | |
* 表示编码对象常住户口所在县(市、旗、区)的行政区划代码,按GB/T2260的规定执行。 | |
* 3、出生日期码(第七位至十四位) | |
* 表示编码对象出生的年、月、日,按GB/T7408的规定执行,年、月、日代码之间不用分隔符。 | |
* 4、顺序码(第十五位至十七位) | |
* 表示在同一地址码所标识的区域范围内,对同年、同月、同日出生的人编定的顺序号, | |
* 顺序码的奇数分配给男性,偶数分配给女性。 | |
* 5、校验码(第十八位数) | |
* (1)十七位数字本体码加权求和公式 S = Sum(Ai * Wi), i = 0, ... , 16 ,先对前17位数字的权求和 | |
* 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 Wi: 7 9 10 5 8 4 2 1 6 3 7 9 10 5 8 4 | |
* 2 (2)计算模 Y = mod(S, 11) (3)通过模得到对应的校验码 Y: 0 1 2 3 4 5 6 7 8 9 10 校验码: 1 0 | |
* X 9 8 7 6 5 4 3 2 | |
