decode.
An item to note with respect to Interleaved 2 of 5 is that the number of digits in
the barcode must be even. This is due to interleaving (one odd digit for every
even digit). As such, sometimes a zero digit must be added to the beginning of
the barcode to make the total digits an even number. It is recommended to use a
check digit and Modulo 10 is generally used for the checksum.
