84731-37-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84731-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,7,3 and 1 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84731-37:
(7*8)+(6*4)+(5*7)+(4*3)+(3*1)+(2*3)+(1*7)=143
143 % 10 = 3
So 84731-37-3 is a valid CAS Registry Number.

Synthesis of Eupolauramine via an Intramolecular Kondrat'eva Pyridine Synthesis
Levin, Jeremy I.,Weinreb, Steven M.
, p. 4325 - 4332 (2007/10/02)
A strategy has been tested for synthesis of annulated pyridines which involves the intramolecular Diels-Alder cycloaddition of an oxazole with an alkene.Oxazole 21 was prepared in four steps from (o-methoxyphenyl)oxazoline 16.Upon heating, 21 produced mix
