EAN 8 7 numbers are transferred for the EAN 8 code. The 8. digit represents the check number.
The even figures of the information have a factor of "3", the uneven figures a factor of "1".
Counting begins from the left. The resulting cross sum is divided by 10. The remaining fig-
ure is subtracted from the modul (10). If the remainder is "0", the check number is also "0".
Example
Information 40123462
