|
|
|
+ * <p>
|
|
|
+ * 顺序码: 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。
|
|
|
+ * </p>
|
|
|
+ * <p>
|
|
|
+ * 1.前1、2位数字表示：所在省份的代码； 2.第3、4位数字表示：所在城市的代码； 3.第5、6位数字表示：所在区县的代码；
|
|
|
+ * 4.第7~14位数字表示：出生年、月、日； 5.第15、16位数字表示：所在地的派出所的代码；
|
|
|
+ * 6.第17位数字表示性别：奇数表示男性，偶数表示女性；
|
|
|
+ * 7.第18位数字是校检码：也有的说是个人信息码，一般是随计算机的随机产生，用来检验身份证的正确性。校检码可以是0~9的数字，有时也用x表示。
|
|
|
+ * </p>
|
|
|
+ * <p>
|
|
|
+ * 第十八位数字(校验码)的计算方法为： 1.将前面的身份证号码17位数分别乘以不同的系数。从第一位到第十七位的系数分别为：7 9 10 5 8 4
|
|
|
+ * 2 1 6 3 7 9 10 5 8 4 2
|
|
|
+ * </p>
|

|
+ * <p>
|
|
|
+ * 2.将这17位数字和系数相乘的结果相加。
|
|

+ * </p>
|
|
|
+ * <p>
|
|
|
+ * 3.用加出来和除以11，看余数是多少？
|
|
|
+ * </p>
|
|
|
+ * 4.余数只可能有0 1 2 3 4 5 6 7 8 9 10这11个数字。其分别对应的最后一位身份证的号码为1 0 X 9 8 7 6 5 4 3
|
|
|
+ * 2。
|
|
|
+ * <p>
|
|
|
+ * 5.通过上面得知如果余数是2，就会在身份证的第18位数字上出现罗马数字的Ⅹ。如果余数是10，身份证的最后一位号码就是2。
