Answer:
The Treasury publishes the OFAC SDN List here.
http://www.treasury.gov/resource-center/sanctions/SDN-List/Pages/default...
It also publishes the Consolidated List that includes other sanctions lists.
http://www.treasury.gov/resource-center/sanctions/SDN-List/Pages/consoli...
The SDN List page includes a link to OFAC's Search Tool that can access both lists.
