curprev 21:5321:53, 14 August 2023 TDLMTH talk contribs 7,985 bytes +301 The original formula "10 - (s mod 10)" returns the range 1-10, not 0-9, and so would cause the check digit calculation to fail; the revised formula accounts for this. The new "other valid formula" gives the same result and is arguably cleaner. The note addresses environments (e.g., the Java programming language) that handle modulo of negative numbers differently. undo Tags: use of deprecated (unreliable) source Visual edit: Switched
