Description

This regex will match an input string of the letter B (or b) followed up by to 7 numerical digits. It will fail if any letter/number/symbol is used other than B (or b) and more than 7 numbers are entered after B (or b). This is simple and was useful for validating a Court Case ID number for users after being entered into a textbox.
