mixed pattern match
I need to grep out patterns that matches the following.

1SR2kW-0003XW-8L

Ie a pattern that contain 16 characters and will always be in the same pattern. 6 character, then a -, then 6 character, then a - then 2 character.

I need a way to grep out like we grep out IP address. Here there are numbers, small letters and caps letters.

Sample output needed
Code:
echo "2011-03-02 04:37:50 [2222] 1SR2kW-0003XW-8L"  | _grep_or_awk_general_command

should give result only 1SR2kW-0003XW-8L
