- Real-time Validation: As users enter their PPSN, the tool checks for the correct format and validates the check digit.
- Responsive Design: The application is designed to be mobile-friendly, ensuring a seamless experience across devices.
- User-Friendly Interface: The validator features a clean and intuitive interface, making it easy to use for everyone.

The validator performs the following checks:
Format Check: Ensures the PPSN is in the correct format, consisting of 7 digits followed by 1 or 2 letters. Check Digit Calculation: Calculates the expected check character using a weighted sum of the digits and a modulus 23 calculation. Second Character Validation: If a second character exists, it checks that it is one of the allowed characters (A, B, W, X, T, Z). The application uses JavaScript to perform these validations in real-time.
