You are violating your own policy by selling the cashiers check to a non-customer. If you are checking OFAC for monetary instruments, then you should check the remitter if it is a non-customer. I would get ID from them. However, you should also consider that if the check is written to a company name, you should not exchange it for a cashiers check unless your bank has a policy to allow cashing of checks made out to a company name.
