The following example illustrates the calculation of the check digits for the symbol CODE 93.
Data
Data Values
C Weights
K Weights
1) For "C", sum the products of the (C WEIGHTS * DATA VALUES).
2) Divide 484 by 47.
3) Therefore, the value of "C" is 14, which corresponds to character E.
4) For "K", sum the products of the (K WEIGHTS * DATA VALUES), starting with the newly
calculated "C" digit.
5) Divide 611 by 47.
6) The value of "K" therefore is 0, corresponding to character 0. Send to the printer:
The Code 93 character table is the same as the Code 3 of 9 character table, except that there are
four additional "control characters" at the end.

(1 * 3) + (2 * 9) + (3 * 38) + (4 * 14) + (5 * 13) + (6 * 24) + (7 * 12) = 484
484 / 47 = 10 remainder 14.
(1*14) + (2*3) + (3*9) + (4*38) + (5*14) + (6*13) + (7*24) + (8*12) = 611
611 / 47 = 13 remainder 0
