125331-32-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125331-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,3,3 and 1 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 125331-32:
(8*1)+(7*2)+(6*5)+(5*3)+(4*3)+(3*1)+(2*3)+(1*2)=90
90 % 10 = 0
So 125331-32-0 is a valid CAS Registry Number.

Synthesis of β-lactams via cycloaddition of hydrazones with phenoxyketene
Sharma,Pandhi
, p. 2196 - 2200 (2007/10/02)
Phenoxyketene is capable of annelating the disubstituted hydrazones to afford stereoselectivity cis-monocyclic β-lactams with a 1-amino functionality. The ease of cycloaddition is governed by substitutents on the azomethine carbon as well as on the hydraz
