CODE 39 MOD 43

 
The Code 39 mod 43 symbology is the same as Code 39, but it has a security check character appended to the code. This check character is the modulus 43 sum of all character values in a given string. Generally speaking, a check character should be used, especially if print quality is less than optimum.
