Regex Expression to validate textbox.

Question

I am trying to validate textbox with regular expression below.

("^(4|5)(?<year>19[5-9][0-9]|[2-9][0-9]{3})(0[1-9]|[1-5][0-9]|6[0-3]{2})[0-9]{6}$");

Where User input starts with either 4 or 5 followed by year from 1950 -9999 followed by 2 digit code and last 6 digits UID.

I am facing issue with 3rd part where it should accept from 01 -63, but it works fine till 59. So I need help with formatting expression to accept 60-63.

Any suggestion and help is appreciated.

When I paste that into Expresso, it says (rightly) "Illegal group syntax" in the second group. There is no regex group that starts "(?" immediately followed by a digit.

("^(4|5)(?<year>19[5-9][0-9]|[2-9][0-9]{3})(0[1-9]|[1-5][0-9]|6[0-3]{2})[0-9]{6}$");

Thanks for response, for some reason in question <year> is missing.

In the group

(0[1-9]|[1-5][0-9]|6[0-3]{2})

Remove the {2}
