Hi ,
I needed to verify that the last 4 digits in a number are 0000.
The
number was of format 999999-0000 so i checked with a regular expression
@"\d-\(0){4}"
but now the '-' will not be there and it always just a number
with last 4 digits as 0 i.e 0000
I am unable to think of a regular expression
to validate this string. any help will be greatly appreciated.

^(\d*(0){4})
