Comparison of checksum procedures by simulation
John M. Carroll, John Cakarnis · Journal of the American Society for Information Science · 1975
Abstract Appending a checksum (also known as checkring] digit[sl, or control digit[s] /sum) to a lengthy non‐mnemonic number sequence represents one technical control over transcription errors. Different checksum procedures are used by different nations (e.g., France, Denmark, Canada) for their personal identifiers (The U.S. does not use a checksum). This study reflects an attempt to discover the most effective procedure.
