55342-93-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55342-93-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,3,4 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 55342-93:
(7*5)+(6*5)+(5*3)+(4*4)+(3*2)+(2*9)+(1*3)=123
123 % 10 = 3
So 55342-93-3 is a valid CAS Registry Number.

SYNTHESIS OF β-HYDROXYALKYLPYRAZOLES BY REACTION OF β-ARYLACRYLOYLOXIRANES WITH HYDRAZINE
Zvonok, A. M.,Kuz'menok, N. M.,Stanishevskii, L. S.
, p. 534 - 537 (2007/10/02)
Reaction of β-arylacryloyloxiranes with hydrazine hydrate takes place via intermediate α,β-epoxyalkylpyrazoles which then undergo intramolecular oxidative-reductive disproportionation to yield β-hydroxyalkylpyrazoles.
