Calculate Digit Verification of CAS Registry Number 16626-70:
(7*1)+(6*6)+(5*6)+(4*2)+(3*6)+(2*7)+(1*0)=113
113 % 10 = 3
So 16626-70-3 is a valid CAS Registry Number.

Synthesis of 2-arylhydrazones of aliphatic fluorine-containing 1,2,3-tricarbonyl compounds and their reactions with dinucleophiles

Kuzueva,Burgart,Saloutin

, p. 673 - 678 (2007/10/03)

New fluorinated 2-arylhydrazones of 1,2,3-tricarbonyl compounds were obtained by coupling fluorine-containing 3-oxo esters, 1,3-diketones, and their copper chelates with aryldiazonium chlorides. Reactions of these arylhydrazones with hydrazine hydrate, phenylhydrazine, thiosemicarbazide, and hydroxylamine gave the corresponding pyrazole and isoxazole derivatives.
