1134954-14-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1134954-14-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,4,9,5 and 4 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1134954-14:
(9*1)+(8*1)+(7*3)+(6*4)+(5*9)+(4*5)+(3*4)+(2*1)+(1*4)=145
145 % 10 = 5
So 1134954-14-5 is a valid CAS Registry Number.

Regioselective synthesis of fluorine-containing indazolones from 2-acylcyclohexane-1,3-diones
Khlebnicova,Isakova,Lakhvich,Kurman
experimental part, p. 301 - 308 (2009/04/03)
New regioisomeric indazolones containing fluorine atoms in the aromatic ring have been synthesized in high yield by the interaction of 2-acylcyclohexane-1,3-diones, and of their enol methyl ethers, obtained by methylating the initial β,β′-triketones with
