A check digit is a data entry control that helps to ensure the accuracy of data entered by verifying the integrity of the data. It calculates a mathematical algorithm using the digits in the data, and then appends this result to the end of the data. When the data is entered, the system recalculates the algorithm using the digits, including the check digit, and compares the result to the original algorithm. If the two results match, the data is considered valid. A check digit would help to prevent similar errors in the future because it adds an extra layer of verification during data entry, making it less likely that errors will slip through undetected.
