How to check if a string is encripted by Laravel Hash?

in my project using Laravel 5.1, beside Hash default class, I also used my library to encrypt password. So how can I check a string be encripted by Laravel Hash or not ? Example :

$2y$10$ug8B6Pxs546eQBNICxsEOOH3NgpXjOIo.g4rf1FPZk2xJncWcFUpu

Thanks for your help.
