A check digit is a numerical value computed and stored along with the input value to provide assurance that the original input value does not contain a transcription error. The check digit is calculated according to a specific algorithm and is typically added to the end of the input value. When the input value is entered into the system, the system calculates the check digit again and compares it to the stored check digit to verify that the input value is correct.
