130657-40-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130657-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,5 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 130657-40:
(8*1)+(7*3)+(6*0)+(5*6)+(4*5)+(3*7)+(2*4)+(1*0)=108
108 % 10 = 8
So 130657-40-8 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.
