Check Digit Verification of cas no

The CAS Registry Mumber 1334335-00-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,4,3,3 and 5 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1334335-00:
(9*1)+(8*3)+(7*3)+(6*4)+(5*3)+(4*3)+(3*5)+(2*0)+(1*0)=120
120 % 10 = 0
So 1334335-00-0 is a valid CAS Registry Number.

Chiral phosphoric acid catalyzed enantioselective transfer hydrogenation of ortho-hydroxybenzophenone N-H ketimines and applications

Nguyen, Thanh Binh,Wang, Qian,Gueritte, Franioise

supporting information; experimental part, p. 9576 - 9580 (2011/10/02)

Unprotected synthesis: The first enantioselective chiral phosphoric acid catalyzed transfer hydrogenation of unprotected ortho-hydroxybenzophenone N-H imines by using a Hantzsch ester as the hydrogen source afforded the corresponding chiral N,O-unprotected ortho-hydroxydiarylmethylamines in high yields with excellent enantioselectivities (see scheme).
