CPF Validation App

Overview

CPF Validation App is a backend application that allows users to enter a Brazilian CPF (Cadastro de Pessoas Físicas) number and verify if it’s valid. The application provides a single route to validate CPF numbers based on Brazilian CPF validation rules.

How It Works

2. Length and Pattern Check: It ensures the CPF has exactly 11 digits and isn’t a sequence of repeating numbers.
3. Verification Digit Calculation: Calculates two verification digits to confirm CPF validity.
