EU VAT Validator

EU VAT validator class. Enter valid EU VAT number and click "Validate".

Please note, that provided validation is not sufficient and does not implement modulo checks specific for each country. For precise modulo check see javascript implementation by John Gardner at http://www.braemoor.co.uk/software/vat.shtml.

Example: valid EU VAT numbers are e.g. ATU99999999 or LU12345678
