Casa now forms part of Eads. See http://www.eads.com Check under "About Military Transport Aircraft".
To the best of my knowledge, Spain uses the CN-235 as a transport. Although a Persuader is available, I don't know if Spain uses this version. Ireland has one at least (see picture at EADS website) and I believe the US Coast Guard was also interested.
For latest news on casa aircraft (particularly the CN-295), check out
At http://www.mde.es/mde/armas/aire/indiaire.htm , you'll find complete information of the Spanish Ministry of Defence of the actual casa aircraft fleet (Aviones de Transporte).
IPTN of Indonesia also constructed the CN-235, but I don't know for sure which versions. I believe they only did a civil version.
