How does PIS/PASEP validation work?
PIS/PASEP has 11 digits: the first 10 form the base number and the last is the check digit, calculated by weighted multiplication by the weights [3,2,9,8,7,6,5,4,3,2] with modulo 11.
The check runs entirely in your browser. No number entered here is sent to servers.
