Check Digit Verification of cas no

The CAS Registry Mumber 840529-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,4,0,5,2 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 840529-68:
(8*8)+(7*4)+(6*0)+(5*5)+(4*2)+(3*9)+(2*6)+(1*8)=172
172 % 10 = 2
So 840529-68-2 is a valid CAS Registry Number.

Highly enantioselective synthesis of (diarylmethyl)amines by rhodium-catalyzed arylation of N-nosylimines using a chiral bicyclo[3.3.0]diene ligand

Wang, Li,Wang, Zhi-Qian,Xu, Ming-Hua,Lin, Guo-Qiang

experimental part, p. 3263 - 3267 (2010/11/18)

A highly efficient asymmetric arylation of N-nosylimines with arylboronic acids catalyzed by a rhodium-diene complex is described. A wide range of enantiopure (98-99% ee) N-(diarylmethyl)nosylamides, as well as (3S)-2-(4-nosyl)-3-phenylisoindolin-1-one, were obtained in high yields (83-99%) under very mild conditions.

An N-linked bidentate phosphoramidite ligand (N-Me-BIPAM) for rhodium-catalyzed asymmetric addition of arylboronic acids to N-sulfonylarylaldimines

Kurihara, Kazunori,Yamamoto, Yasunori,Miyaura, Norio

experimental part, p. 260 - 270 (2009/09/06)

A chiral N-linked C2-symmetric bidentate phosphoramidite (N-Me-BIPAM) was newly developed for the rhodium-catalyzed enantioselective addition of arylboronic acids to N-sulfonylimines. This ligand achieved high enantioselectivities in a range of
