Check Digit Verification of cas no

The CAS Registry Mumber 851513-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,1,5,1 and 3 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 851513-48:
(8*8)+(7*5)+(6*1)+(5*5)+(4*1)+(3*3)+(2*4)+(1*8)=159
159 % 10 = 9
So 851513-48-9 is a valid CAS Registry Number.

A room-temperature protocol for the rhodium(I)-catalyzed addition of arylboron compounds to sulfinimines

Bolshan, Yuri,Batey, Robert A.

, p. 1481 - 1484 (2005)

(Chemical Equation Presented) The addition of organoboronic acids to chiral sulfinimines proceeds under mild conditions at room temperature, using Rh(I) catalysis in the absence of external phosphine ligands. Clean reaction only occurs in the presence of

Conversion of 1,3-disubstituted arenes to chiral α,α-diaryl methylammonium chlorides using arene borylation

Boebel, Timothy A.,Hartwig, John F.

, p. 6824 - 6830 (2008/09/21)

A two-step conversion of 1,3-disubstituted arenes to chiral α,α-diaryl methylammonium chlorides is described. In this procedure, arenes are converted to aryl boronic esters by iridium-catalyzed borylation, and the aryl boronic esters are converted to enantioenriched amines by subsequent rhodium-catalyzed addition to chiral tert-butanesulfinimes.
