Check Digit Verification of cas no
The CAS Registry Mumber 2797-79-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,9 and 7 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2797-79:
(6*2)+(5*7)+(4*9)+(3*7)+(2*7)+(1*9)=127
127 % 10 = 7
So 2797-79-7 is a valid CAS Registry Number.

Synthesis of polyfluorinated arylhydrazines, arylhydrazones and 3-methyl-1-aryl-1H-indazoles
Politanskaya, Larisa,Bagryanskaya, Irina,Tretyakov, Evgeny
, p. 48 - 57 (2018/08/17)
Polyfluorinated arylhydrazones were synthesized starting from 1-(4-amino-tetrafluorophenyl)ethanone and polyfluorinated arylhydrazines by action of p-toluenesulfonic acid in good yields. The resulting mixtures of E- and Z-isomers were next treated with K2CO3 in MeCN at room temperature. Under these mild reaction conditions Z-isomers underwent intramolecular nucleophilic cyclization to form 3-methyl-1-aryl-1H-indazole derivatives, while E-isomers were not active and were isolated unchanged. Molecular and crystal structures of prepared polyfluorinated (E)-arylhydrazones as well as selected 3-methyl-1-aryl-1H-indazoles were solved by the X-ray diffraction analysis. Meanwhile, the polyfluorinated acetophenone reacted with hydrazine in THF in the absence of a catalyst through a condensation–nucleophilic substitution cascade process to form a 3-methyl-1H-indazole derivative in excellent yield.
