Japanese Patent JPS5750287
Kind Code:
B2
Abstract:
There is provided a calculator for calculating check digits which are obtained from code numbers according to a modulus 10, modulus 11 or the like check. In accordance with one embodiment of the invention, the desired check digit original numerals are indicated in response to the determination of a code number and weights and the desired check digit is readily obtained from the sum of the check digit original numerals. In accordance with another embodiment, the desired check digit is directly indicated in response to the setting of a code number.
