125647-92-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 125647-92-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,4 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 125647-92:
(8*1)+(7*2)+(6*5)+(5*6)+(4*4)+(3*7)+(2*9)+(1*2)=139
139 % 10 = 9
So 125647-92-9 is a valid CAS Registry Number.

2-Polyfluoroalkylchromones 14.* Synthesis of 4-chloro-3(5)-(2- hydroxyaryl)-5(3)-polyfluoroalkylpyrazoles
Sosnovskikh,Usachev,Sizov
, p. 508 - 510 (2003)
3-Chloro-2-polyfluoroalkyl- and 3-chloro-6-nitro-2- polyfluoroalkylchromones were synthesized. These compounds react with N 2H2·2HCl on boiling in ethanol to form 4-chloro-3(5)-(2-hydroxyaryl)-5(3)-polyfluoroalkylpyrazoles.
