Example of check digit calculation:

The following characters are provided for coding the start and stop characters:

– Start character: a, b, c, d or s (hexadecimal: 61, 62, 63, 64 or 73)

– Stop character: e or f (hexadecimal: 65 or 66)

Plain text : C + O + D + E SP 9 3 W I

Check character

Check digit C : W (weighting of 1, 2, ... 10, 1, 2, ... from right to left)

Check digit K : I (weighting of 1, 2, ... 15, 1, 2, ... from right to left)

Information char seq. : C + O + D + E SP 9 3

Reference values : 12 41 24 41 13 41 14 38 9 3

Weighting factors

for check digit C : 10 9 8 7 6 5 4 3 2 1

Weighting factors

for check digit K : 11 10 9 8 7 6 5 4 3 2 1

Sum of products

for check digit C :

(12*10) + (41*9) + (24*8) + (41*7) + (13*6) + (41*5)

+ (14*4) + (38*3) + (9*2) + (3*1) = 1442

Modulo 47 : 1442 mod 47 = 32 (1442/47 = 30, remainder 32)

Check digit C : W (W corresponds to the reference number 32)

Sum of products

for check digit K

: (12*11) + (41*10) + (24*9) + (41*8) + (13*7) + (41*6)

+ (14*5) + (38*4) + (9*3) + (3*2) + (32*1) = 1710

Modulo 47 : 1710 mod 47 = 18 (1770/47 = 36, remainder 18)

Check digit K : I (I corresponds to the reference number 18)
