Checksum calculation for the symbol Cat

Data C <CTRL> + A <CTRL> + T "C" "K"

Data Values 12 46 10 46 29

C Weights543 2 1

K Weights654 3 21

1) For "C", sum the products of the (C WEIGHTS * DATA VALUE S).

(1 * 29) + (2 * 46) + (3 * 10) + (4 * 46) + (5 * 12) = 395

2) Divide 395 by 47.

395 / 47 = 8 remainder 19.

Therefore, the value of "C" is 19, which corresponds to c haracter J.

3) For "K", sum the products of the (K WEIGHTS * DATA VALUES) , starting with the newly

calculated "C" digit.

(1*19) + (2*29) + (3*46) + (4*10) + (5*46) + (6*12) = 557

4) Divide 557 by 47.

611 / 47 = 11 remainder 40

5) The value of “K” therefore is 40, corresponding to charac ter /. Send to the printer:
