Check Digit Verification of cas no
The CAS Registry Mumber 80171-21-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,1,7 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 80171-21:
(7*8)+(6*0)+(5*1)+(4*7)+(3*1)+(2*2)+(1*1)=97
97 % 10 = 7
So 80171-21-7 is a valid CAS Registry Number.

Ring Monofluorinated Hydroxypyrazoles
Kagaruki, Serry R. F.,Kitazume, Tomoya,Ishikawa, Nobuo
, p. 3221 - 3222 (2007/10/02)
3-Alkyl(or aryl)-4-fluoro-5-hydroxypyrazoles and their 1-methyl derivatives were prepared by the reaction of methyl α-fluoro-β-alkyl(or aryl)-β-keto esters with hydrazine hydrate or methylhydrazine in ethanol.The reaction of arylhydrazines with α-fluoro-β-keto esters gave only hydrazones which could not be cyclized to pyrazoles.
