1380397-32-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1380397-32-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,0,3,9 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1380397-32:
(9*1)+(8*3)+(7*8)+(6*0)+(5*3)+(4*9)+(3*7)+(2*3)+(1*2)=169
169 % 10 = 9
So 1380397-32-9 is a valid CAS Registry Number.

Absolute asymmetric synthesis of tertiary α-amino acids

Mai, Thi Thoa,Branca, Mathieu,Gori, Didier,Guillot, Régis,Kouklovsky, Cyrille,Alezra, Valérie

, p. 4981 - 4984 (2012)

Frozen: The spontaneous crystallization of an achiral compound in a chiral conformation is used as the unique source of chirality in an absolute asymmetric synthesis of tertiary amino acids. The dynamic axial chirality of tertiary aromatic amides is frozen in a crystal (see picture) and is responsible for the stereoselectivity of the deprotonation/alkylation (see scheme). α-Amino acid derivatives are synthesized in up to 96% ee.
