Check Digit Verification of cas no

The CAS Registry Mumber 250591-26-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,0,5,9 and 1 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 250591-26:
(8*2)+(7*5)+(6*0)+(5*5)+(4*9)+(3*1)+(2*2)+(1*6)=125
125 % 10 = 5
So 250591-26-5 is a valid CAS Registry Number.

A concise synthesis of homochiral sedamines and related alkaloids. A new reductive application of Jacobsen's catalyst

Yu, Chu-Yi,Meth-Cohn, Otto

, p. 6665 - 6668 (2007/10/03)

Two methods for the generation of both enantiomers of sedamine [1- methyl-2-(2-phenyl-2-hydroxy-1-ethyl)piperidine] in high optical purity have been elaborated. The first utilises the lipase-mediated kinetic resolution of racemic acetates and the second involves the NaBH4 mediated reduction of ketones catalysed by Jacobsen's catalyst. Some related applications of these reactions are also disclosed.
