Check Digit Verification of cas no

The CAS Registry Mumber 957109-98-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,5,7,1,0 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 957109-98:
(8*9)+(7*5)+(6*7)+(5*1)+(4*0)+(3*9)+(2*9)+(1*8)=207
207 % 10 = 7
So 957109-98-7 is a valid CAS Registry Number.

Dynamic kinetic resolution allows a highly enantioselective synthesis of cis-α-aminocycloalkanols by ruthenium-catalyzed asymmetric hydrogenation

Liu, Sheng,Xie, Jian-Hua,Wang, Li-Xin,Zhou, Qi-Lin

, p. 7506 - 7508 (2007)

(Chemical Equation Presented) Resolutely dynamic hydrogenation: A highly efficient asymmetric hydrogenation of racemic N,N-disubstituted α-aminocycloalkanones involving dynamic kinetic resolution in the presence of a ruthenium catalyst gives chiral α-aminocycloalkanols with excellent enantioselectivities and cis diastereoselectivities (see scheme). A synthesis of optically pure U-(-)-50488 based on this reaction is reported.
