an/rn

I purchased a banklog that comes with only the 'login and password'. Please can anyone tell an app or website that I can used to view the an/rn. Or how to cash out with those kind of banklogs Please.

I bought an active an/rn with insta yodlee and i plan to cashout with reverse ach by creating another drop in the name of the bank holder and linking via micro deposits but i just wanted to know if anyone had any info to share on this process and or problems i could run into and avoid.
