 **isLicensePlate(str [, locale])**     | check if string matches the format of a country's license plate.<br/><br/>(locale is one of `['de-DE', 'de-LI', 'pt-PT', 'sq-AL', 'pt-BR'']` or `any`). 
 **isLocale(str)**                       | check if the string is a locale
 **isLowercase(str)**                    | check if the string is lowercase.
-**isLuhn(str)**                         | check if the string is a valid [Luhn](https://en.wikipedia.org/wiki/Luhn_algorithm).
 **isMACAddress(str)**                   | check if the string is a MAC address.<br/><br/>`options` is an object which defaults to `{no_separators: false}`. If `no_separators` is true, the validator will allow MAC addresses without separators. Also, it allows the use of hyphens, spaces or dots e.g  '01 02 03 04 05 ab', '01-02-03-04-05-ab' or '0102.0304.05ab'.
 **isMagnetURI(str)**                      | check if the string is a [magnet uri format](https://en.wikipedia.org/wiki/Magnet_URI_scheme).
 **isMD5(str)**                          | check if the string is a MD5 hash.<br/><br/>Please note that you can also use the `isHash(str, 'md5')` function. Keep in mind that MD5 has some collision weaknesses compared to other algorithms (e.g., SHA).
