    Closer to being perfect is the LUN 10 checksum (sanity check on credit card numbers)... but even that can have a failure.

    Just in case anyone else is interested in finding out more regarding the checksum Jeff mentions I found it is actually:

    LUHN10 checksum

    Heh... thanks for the correction... I ate garlic and didn't want to breath on anyone too hard so I left the "H" out. 😛

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
