Hi,
You can do like below

var regExp = new RegExp("^(?!(\d)\1+$)(?!(012345678901|123456789012|234567890123|345678901234|456789012345|567890123456|678901234567|789012345678|890123456789|901234567890)$)(?!\d{9}000$)\d{12}$");
var result=regExp.test("1234");

Hi Rangnath,

Your Regex is totally fine, you just need to pu it a proper JavaScript syntax:
------------------------------------------
var myregexp = /^(?!(\d)\1+$)(?!(012345678901|123456789012|234567890123|345678901234|456789012345|567890123456|678901234567|789012345678|890123456789|901234567890)$)(?!\d{9}000$)\d{12}$/;
------------------------------------------

Hope it helps!
