As such it has two check digits. >>> calc_check_digits('99991234567890121414') '90' >>> validate('9999123456789012141490') '9999123456789012141490' >>> calc_check_digits('4354111611551114') '31' >>> validate('08686001256515001121751') '08686001256515001121751' >>> calc_check_digits('22181321402534321446701611') '35' ) annotations)*c2djd|DS)z0Prepare the number to its base10 representation.c3FK|]}tt|dyw)$N)strint).0xs _/var/www/html/myprovider/mon_projet_qr/lib/python3.12/site-packages/stdnum/iso7064/mod_97_10.py z_to_base10..,s)C2J)s!)joinnumbers r _to_base10r*s 77)!') ))c0tt|dzS)zCCalculate the checksum.
