143140-31-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143140-31-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,1,4 and 0 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143140-31:
(8*1)+(7*4)+(6*3)+(5*1)+(4*4)+(3*0)+(2*3)+(1*1)=82
82 % 10 = 2
So 143140-31-2 is a valid CAS Registry Number.

SYNTHESIS OF A BICYCLIC γ-LACTAM DIPEPTIDE ANALOGUE
Baldwin, Jack E.,Lee, Victor,Schofield, Christopher J.
, p. 903 - 906 (2007/10/02)
The asymmetric synthesis of a bicyclic γ-lactam analogue of a dipeptide, in which the key step was the bis-alkylation of an optically active diphenyloxazinone chiral glycine anion equivalent is described.
