Check Digit Verification of cas no

The CAS Registry Mumber 102595-81-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,5,9 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 102595-81:
(8*1)+(7*0)+(6*2)+(5*5)+(4*9)+(3*5)+(2*8)+(1*1)=113
113 % 10 = 3
So 102595-81-3 is a valid CAS Registry Number.

Reaction of 1,5-Diphenyl-1,4-pentadien-3-one and 1,5-Diphenyl-1-penten-4-yn-3-one with monosubstituted hydrazines

Botvinnik,Blandov,Kuznetsov

, p. 421 - 425 (2001)

Phenyl-and isopropylhydrazines react with 1,5-diphenyl-1,4-pentadien-3-one to give 4,5,6,7-tetrahydroindazole derivatives instead of the expected 4,5-dihydropyrazoles. The reaction of phenylhydrazine with 1,5-diphenyl-1-penten-4-yn-3-one leads to formation of 1,5-diphenyl-3-phenylethynyl-4,5-dihydropyrazole. 2,4-Dinitrophenylhydrazine reacts with 1,5-diphenyl-1-penten-4-yn-3-one, affording the corresponding unsaturated hydrazone rather than pyrazole derivative.
