112545-21-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112545-21-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,5,4 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 112545-21:
(8*1)+(7*1)+(6*2)+(5*5)+(4*4)+(3*5)+(2*2)+(1*1)=88
88 % 10 = 8
So 112545-21-8 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.
