this covers criteria , tests few numbers. not specify reason number being invalid - leave you.

var numarr = ["1111111111", "0123456789", "9876543210", "8682375827", "83255"];  (var = 0; < numarr.length; i++) {     console.log(numarr[i] + " " + validate(numarr[i])); }  function validate(num) {     if ((num.match(/^[6-9]\d{9}$/) && (!num.match(/^([0-9])\1{9}$/))) && (!isincr(num) && (!isdecr(num)))) {         return ( "valid") ;     } else {         return ( "not valid") ;     } }  function isincr(num) {     (var = 1; < num.length; i++) {         if (num[i] == parseint(num[i - 1]) + 1) {             continue;         } else {             return false;         }     }     return true; }  function isdecr(num) {     (var = 1; < num.length; i++) {         if (num[i] == parseint(num[i - 1]) - 1) {             continue;         } else {             return false;         }     }     return true; }
