MEMORANDUM ***
Gevork Bebedjian, a native and citizen of Armenia, petitions for review of the Board of Immigration Appeals’ (“BIA”) dismissal of his appeal from an Immigration Judge’s (“IJ”) denial of his applications for asylum, withholding of deportation, and relief under the Convention Against Torture (“CAT”). Because the transitional rules apply, see Kalaw v. INS, 133 F.3d 1147, 1150 (9th Cir.1997), we have jurisdiction under 8 U.S.C. § 1105a(a). We review for substantial evidence an adverse credibility determination. Mejia-Paiz v. INS, 111 F.3d 720, 723 (9th Cir.1997). We deny the petition for review.
The BIA based its adverse credibility finding on numerous and substantial inconsistencies in Bebedjian’s testimony that went to the heart of his asylum claim. See Chebchoub v, INS, 257 F.3d 1038, 1043 *612(9th Cir.2001). Accordingly, substantial evidence supports the BIA’s denial of Bebedjian’s application for asylum and withholding of deportation. See id. at 1045.
We do not consider Bebedjian’s contention that the BIA violated his due process rights by not addressing his CAT claim because Bebedjian failed to raise this issue on appeal to the BIA. See Vargas v. INS, 831 F.2d 906, 907-08 (9th Cir.1987) (failure to raise an issue before the BIA constitutes failure to exhaust administrative remedies and deprives this court of jurisdiction to hear that issue). Although due process claims are generally exempt from this procedural rule, Bebedjian cannot obtain review merely by alleging that this error violates due process. See id.
Bebedjian’s remaining contentions also lack merit.
PETITION FOR REVIEW DENIED.
