Check Digit Verification of cas no

The CAS Registry Mumber 1263288-53-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,2,8 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1263288-53:
(9*1)+(8*2)+(7*6)+(6*3)+(5*2)+(4*8)+(3*8)+(2*5)+(1*3)=164
164 % 10 = 4
So 1263288-53-4 is a valid CAS Registry Number.

Reactions of polyfluorinated chalcones with hydrazine hydrate and phenylhydrazine

Smuilovich,Orlova,Karpova,Shakirov,Shelkovnikov

experimental part, p. 1408 - 1413 (2011/04/16)

Polyfluorinated di- and triarylpyrazolines were synthesized by the reactions of polyfluorinated chalcones with hydrazine hydrate and phenylhydrazine, respectively. Reactions of benzyl-idenepolyfluoroacetophenones with phenylhydrazine resulted in the mixtures of isomeric 1,5-diphenyl-3- polyfluoroaryl-and 1,3-diphenyl-5-polyfluoroarylpyrazolines. Fluorescence properties of the synthesized triarylpyrazolines were studied.
