Hi,

This code is working for c#. when we are coming to java script it is not working.

regular expression in c#.
string regExp ="^(?!(\d)\1+$)(?!(012345678901|123456789012|234567890123|345678901234|456789012345|567890123456|678901234567|789012345678|890123456789|901234567890)$)(?!\d{9}000$)\d{12}$"
