CTR is not required. The customer walked in with a negotiable instrument and he walked out with one. The $10,000+ limit was not hit.
If you suspect this is an illegal transaction in some way, then it would be reportable on a SAR. On the surface, the person wanted good funds without the hastle of waiting for a personal check to clear. Took some cash and wanted the balance in a cashiers check. Seems OK to me.
