Check Digit Verification of cas no

The CAS Registry Mumber 93273-86-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,2,7 and 3 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 93273-86:
(7*9)+(6*3)+(5*2)+(4*7)+(3*3)+(2*8)+(1*6)=150
150 % 10 = 0
So 93273-86-0 is a valid CAS Registry Number.

SYNTHESIS OF DIASTEREO- AND ENANTIOMERICALLY PURE α-AMINO-γ-OXO ACID ESTERS BY REACTION OF ACYLIMINOACETATES WITH ENAMINES DERIVED FROM 6-MEMBERED KETONES

Kober, Reiner,Papadopoulos, Kyriakos,Miltz, Wolfgang,Enders, Dieter,Steglich, Wolfgang,et al.

, p. 1693 - 1702 (2007/10/02)

A new efficient diastereo- and enantioselective synthesis of α-amino-γ-oxo acid esters by reaction of acyliminoacetates with enamines is described.By employing the concept of double stereodifferentiation, complete asymmetric induction (de=ee >/= 99.9 percent) for the C-C bond formation is obtained.Desulphurization of a sulphur containing product leads to the corresponding acyclic amino acid derivatives.The virtually complete anti-diastereo- and enantioselectivities are interpreted by a Diels-Alder like transition state.
