Offline validator for a Guatemalan CUI (Código Único de Identificación), the 13-digit national ID number. Parses the 13 digits into an 8-digit correlative, a 1-digit check digit, a 2-digit department code and a 2-digit municipality code, recomputes the check digit using the published weighted mod-11 formula (weights 2-9 over the 8 correlative digits, mod 11, 10→0) and compares it, returning validity plus the parsed components.
