Check Digit Verification of cas no

The CAS Registry Mumber 944419-22-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,4,4,1 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 944419-22:
(8*9)+(7*4)+(6*4)+(5*4)+(4*1)+(3*9)+(2*2)+(1*2)=181
181 % 10 = 1
So 944419-22-1 is a valid CAS Registry Number.

Organocatalytic asymmetric reaction cascade to substituted cyclohexylamines

Zhou, Jian,List, Benjamin

, p. 7498 - 7499 (2008/02/10)

We report a new strategy for organocatalytic cascade reactions. Accordingly, enamine catalysis, iminium catalysis, and Bronsted acid catalysis can work in concert in a highly enantioselective organocatalytic cascade sequence toward chiral cis-3-substituted cyclohexylamines. We found that an achiral amine in combination with a catalytic amount of a chiral Bronsted acid can accomplish an aldol addition-dehydration-conjugate reduction-reductive amination to provide potential intermediates of pharmaceutically active compounds in good yields and excellent enantioselectivities.
