(E) Modulus 43
Modulus 43 is the check digit computation method used in the CODE-39 symbology.
Each of 43 characters is assigned each value. All characters are converted into the value
and computed.
The following example uses the ID number 258-416.
(1) Add the values of all the data characters. The numerical value of each of the data
characters is given below:

Sum = 2+5+8+36+4+1+6 = 62
(2) Divide the sum by 43 and get the remainder.
62/43 = 1; remainder = 19
(3) Find the check-character. The check-character is that character whose value is
equal to the remainder. In this example, the letter "J" has the value of 19 which is
equal to the remainder. Therefore "J" is the check-character.
(4) This check-character is appended to the ID number, after the least significant digit.
The bar-code label is now "258-416J".
