Watch a tutorial

Calculate verifier (checksum) digits.

 

Parameter

 Description
Digit Variable that will receive the calculated digit.
Rest Variable that will receive the "rest" of the division.
Value Value or Variable to calculate the digit.
Module Value or Variable containing the module to be used. The default value is the module "11".
Weights Value or Variable containing the weights to be used. The default value is the "98765432".
Type Value or Variable containing the parcels calculation to be used: 1 to the normal sum of the values of the parcels and 2 to the sum of each algorithm of the parcels. The default value is "1".

 

Ex. 1:
sc_calc_dv({my_dv}, {my_rest}, 1234567, 11, 98765432, 1);
Parcels calculation: 7x2= 14 ; 6x3=18 ; 5x4=20 ; 4x5=20 ; 3x6=18 ; 2x7=14 ; 1x8=8
Parcels sum : 14 + 18 + 20 + 20 + 18 + 14 + 8 = 112
Rest of the division of 112 / 11 = 2
Digit: 11 - 2 = 9

 

Ex. 2:
sc_calc_dv({my_dv}, {my_rest}, 1234567, 10, 12, 2);
Parcels calculation: 7x2= 14 ; 6x1=6 ; 5x2=10 ; 4x1=4 ; 3x2=6 ; 2x1=2 ; 1x2=2
Parcels sum: 1 + 4 + 6 + 1 + 0 + 4 + 6 + 2 + 2 = 26
Rest of the division of 26 / 10 = 6
Digit: 10 - 6 = 4
