The friend code can be derived from the textual form of "1234-5678-9012" by stripping the slashes and then converting the string to an integer.
This function just calls [[FRDU:PrincipalIdToFriendCode]] with the lower half of the friend code and checks if the checksum byte returned matches the input.
