MEMORANDUM **
Juan Garcia-Cortez appeals from the 168-month sentence imposed after his guilty-plea conviction for conspiracy to possess and distribute pseudoephedrine, knowing and having reasonable cause to believe that the pseudoephedrine would be used to manufacture methamphetamine, in violation of 21 U.S.C. § 846. We have jurisdiction under 28 U.S.C. § 1291 and affirm.
Garcia-Cortez contends that retroactive application of the remedial portion of United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), violated his due process rights and the ex post facto clause. Both contentions are foreclosed by United States v. Dupas, 419 F.3d 916, 920-21, 924 (9th Cir.2005), and United States v. Staten, 450 F.3d 384, 388 (9th Cir.2006).
Garcia-Cortez further contends the district court clearly erred by attributing to him the entire amount of pseudoephedrine seized by investigators. The court reasonably determined from telephone calls between Garcia-Cortez and his associates and from proffered admissions by a co-defendant that Garcia-Cortez agreed to purchase the entire amount. See United States v. Asagba, 77 F.3d 324, 326 (9th Cir.1996). Accordingly, it was not unreasonable for the district court to base the sentence on the entire amount of pseudoephedrine seized. See United States v. Plouffe, 445 F.3d 1126, 1131 (9th Cir.2006).
AFFIRMED.
