Accumulate Mode - Worth Data RF Terminal 7000 Owner's Manual

Take the sum of the values assigned to each character:
1 + 2 + 3 + 33 + 34 + 35 = 108
1 2
Divide the sum by 43: (thus the name modulus 43)
108/43 = 2 with a Remainder of 22
Find the character corresponding with the remainder.
M (value 22) is the CHECK CHARACTER
The data becomes 123XYZM, with M added as the Mod-43 check character.
