Enable validation of optional checksum
Public Property ValidateOptChecksum As EBoolean
For Code 39 and for Interleaved 2 of 5 barcodes, this property, when set to true, requires verification of the checksum, according to the standard specifications of each symbology. The default value is false because, in practice, checksums are seldom used with these codes. For other symbologies the value of this property is ignored, because their checksums are either nonexistent or mandatory.
