A CLABE (Clave Bancaria Estandarizada) has three digits for the institution, three for the plaza or city, eleven for the account and a final control digit. Transfers through SPEI, Mexico's interbank system, are addressed with it.
Each of the first seventeen digits is multiplied by 3, 7 and 1 in turn, keeping only the last digit of each product. The control digit is whatever brings the total up to the next multiple of ten.
The institution is read from the first three digits, using Banxico's participant list as published in Cuenca's open-source CLABE library. It covers banks and the newer financial institutions that hold accounts.
