When using ARCUITField and enter a valid CUIT terminated (that is, check digit) in 0 or 9, the clean method raise a Validation error message. To replicate the bug, just enter a valid cuit number with the format XX-XXXXXXXX-0, and you will see the error ""Invalid CUIT"". The problem is in the _calc_cd(self, cuit) method, that not take care of this two special cases. More info in [http://es.wikipedia.org/wiki/C%C3%B3digo_%C3%9Anico_de_Identificaci%C3%B3n_Tributaria] A quick fix for this could be: {{{ def _calc_cd(self, cuit): mults = (5, 4, 3, 2, 7, 6, 5, 4, 3, 2) tmp = sum([m * int(cuit[idx]) for idx, m in enumerate(mults)]) aux_cd = 11 - tmp % 11 if aux_cd == 11: aux_cd = 0 elif aux_cd == 10: aux_cd = 9 return str(aux_cd) }}} Thanks, " Bug closed contrib.localflavor 1.4 Normal fixed ARCUITField, localflavor.ar Accepted 1 0 1 0 1 0
