Calculate Digit Verification of CAS Registry Number 1247949-37:
(9*1)+(8*2)+(7*4)+(6*7)+(5*9)+(4*4)+(3*9)+(2*3)+(1*7)=196
196 % 10 = 6
So 1247949-37-6 is a valid CAS Registry Number.

Chiral phosphoric acid-catalyzed enantioselective transfer hydrogenation of ortho-hydroxyaryl alkyl N - H ketimines

Nguyen, Thanh Binh,Bousserouel, Hadjira,Wang, Qian,Gueritte, Francoise

, p. 4705 - 4707 (2010)

The first enantioselective chiral phosphoric acid-catalyzed transfer hydrogenation of unprotected ortho-hydroxyaryl alkyl N - H ketimines using Hantszch di-tert-butyl ester as a reductant is reported. A variety of ortho-hydroxybenzylamines were obtained in good to excellent yields and enantiomeric excesses.
