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.

“He took control of me for forty-five minutes. This time I’ll have control over him for the rest of his life. If he gets out fifteen years from now, I’ll know. I’ll *check* on him every three months through police computers. If he makes one mistake he’s going down again. I’ll make sure. I’m his worst enemy now.”
