Check digit

Eine aus dem Rest der Kennung berechnete Ziffer, die Tippfehler vor jedem Lookup abfängt. Jeder Standard hat seine Regel: ISO 6346 mod-11 mit Buchstabenwerten, UPU S10 gewichtetes mod-11 mit 10→0/11→5, SSCC GS1 mod-10, IMO gewichtete Summe 7..2, IATA AWB mod 7. TrackJet implementiert alle fünf selbst.
