Check "Wallet Details" at bitaddress.org.
However, in general, you should never trust any site that accepts a private key in any form.
Also, you should never disclose a private key like you have here. It is easy for anyone to steal any funds that are at its address, now or any time in the future.
Here is what that page shows:
