151929-39-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 151929-39-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,1,9,2 and 9 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 151929-39:
(8*1)+(7*5)+(6*1)+(5*9)+(4*2)+(3*9)+(2*3)+(1*9)=144
144 % 10 = 4
So 151929-39-4 is a valid CAS Registry Number.

Asymmetric Synthesis of Both Enantiomers of Vigabatrin: An Approach Using Methionine as the Chiral Pool
Wei, Zhong-Yong,Knaus, Edward E.
, p. 5569 - 5578 (2007/10/02)
Both enantiomers of the potent GABA-T inhibitor, 4-amino-5-hexenoic acid (2), were prepared in five steps from (R)- or (S)-methionine using a one-pot reduction-homologation of an α-amino ester as the key reaction step.
