Check Digit Verification of cas no

The CAS Registry Mumber 1643933-44-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,3,9,3 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1643933-44:
(9*1)+(8*6)+(7*4)+(6*3)+(5*9)+(4*3)+(3*3)+(2*4)+(1*4)=181
181 % 10 = 1
So 1643933-44-1 is a valid CAS Registry Number.

Asymmetric synthesis of 2-heteroaryl cyclic amines: Total synthesis of (-)-anabasine

Sallio, Romain,Lebrun, Stephane,Gigant, Nicolas,Gillaizeau, Isabelle,Deniau, Eric

, p. 4381 - 4388 (2014/07/21)

A new and concise method for the synthesis of enantioenriched 2-heteroaryl cyclic amines was developed through an intramolecular chirality transfer. The influence of the nature of both ring size and heteroaryl moiety was investigated. The versatility of this reaction was demonstrated by the enantioselective synthesis of (-)-anabasine. Copyright
