A check digit is a form of redundancy check used for error detection, the decimal equivalent of a binary checksum. It consists of a single digit computed from the other digits in the message.
With a check digit, one can detect simple errors in the input of a series of digits, such as a single mistyped digit or some permutations of two successive digits.
