95503-73-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 95503-73-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,5,0 and 3 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 95503-73:
(7*9)+(6*5)+(5*5)+(4*0)+(3*3)+(2*7)+(1*3)=144
144 % 10 = 4
So 95503-73-4 is a valid CAS Registry Number.

ASYMMETRIC SYNTHESIS WITH CHIRAL HYDROXYLAMINES. SYNTHESIS OF OPTICALLY PURE 4-SUBSTITUTED AZETIDINONES
Baldwin, S. W.,Aube, J.
, p. 179 - 182 (2007/10/02)
The reaction between β-substituted acrylate esters and α-methylbenzyl hydroxyl amine affords diastereoisomeric 5-isoxazolidinones, convenient precursors of simple optically pure 2-azetidinones.
