从名字上我猜你是南方非洲，所以这里有一些用于验证RSA ID的JavaScript代码。它检查有效日期和最后的检查数

From the name I guess you are South African, so here is some javascript code for validating an RSA id. It checks for valid date and the checkdigit at the end

function ValidateRSAIDNo(id) {
       try {
           if (id.length != 13) return false;

           var y1o = id.substring(0, 1)
           var y2e = id.substring(1, 2)
           var m1o = id.substring(2, 3)
           var m2e = id.substring(3, 4)
           var d1o = id.substring(4, 5)
           var d2e = id.substring(5, 6)
           var go = id.substring(6, 7)
           var s1e = id.substring(7, 8)
           var s2o = id.substring(8, 9)
           var s3e = id.substring(9, 10)
           var co = id.substring(10, 11)
           var ae = id.substring(11, 12)
           var z = id.substring(12, 13)

           var A = 0;
           A = parseInt(A) + parseInt(y1o) + parseInt(m1o) + parseInt(d1o) + parseInt(go) + parseInt(s2o) + parseInt(co);
           var B1 = y2e + m2e + d2e + s1e + s3e + ae;
           var B2 = B1 * 2;
           var i = 0;
           var B3 = 0;
           var B2string = B2.toString();
           while (B2string.length > i) {
               var x = B2string.substring(i, i + 1);
               B3 = B3 + parseInt(x);
               i = i + 1;
           }

           var C = A + B3;
           var Cstring = C.toString();
           var secNo = Cstring.substring(1, 2);
           var D = 10 - parseInt(secNo);
           while (D >= 10) D = D - 10;
           if (D == z) {
               //test for valid date in 1900
               var valid = true;
               var bd = new Date('19' + y1o + y2e, parseInt(m1o + m2e) - 1, d1o + d2e);
               if ((bd == 'NaN') | (bd == 'Invalid Date')) valid = false;
               else if (bd.getFullYear() != parseInt('19' + y1o + y2e)) valid = false;
               else if (bd.getMonth() + 1 != parseInt(m1o + m2e)) valid = false;
               else if (bd.getDate() != parseInt(d1o + d2e)) valid = false;
               //if invalid test again in 2000
               valid = true;
               bd = new Date('20' + y1o + y2e, parseInt(m1o + m2e) - 1, d1o + d2e);
               if ((bd == 'NaN') | (bd == 'Invalid Date')) valid = false;
               else if (bd.getFullYear() != parseInt('20' + y1o + y2e)) valid = false;
               else if (bd.getMonth() + 1 != parseInt(m1o + m2e)) valid = false;
               else if (bd.getDate() != parseInt(d1o + d2e)) valid = false;
               //return result
               return valid;
           }
           else {
               return false;
           }
       }
       catch (e) {
           return false;
       }
   }
