Check Digit Verification of cas no

The CAS Registry Mumber 1227798-65-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,7,7,9 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1227798-65:
(9*1)+(8*2)+(7*2)+(6*7)+(5*7)+(4*9)+(3*8)+(2*6)+(1*5)=193
193 % 10 = 3
So 1227798-65-3 is a valid CAS Registry Number.

Rhodium-catalyzed asymmetric arylation of N -(tert -butanesulfinyl)imines with sodium tetraarylborates

Reddy, Leleti Rajender,Gupta, Aditya P.,Villhauer, Eric,Liu, Yugang

, p. 1095 - 1100 (2012/03/12)

A diastereoselective rhodium-catalyzed arylation of N-(tert-butanesulfinyl) imines with sodium tetraarylborates is described. This method is general for constructing various chiral α-branched amines and 2-substituted pyrrolidines with high diastereoselectivity. A practical asymmetric approach to access chiral amines has been developed involving the use of air-stable Rh catalysts and reagents and in the absence of an external ligand.
