Check Digit Verification of cas no
The CAS Registry Mumber 92939-26-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,9,3 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 92939-26:
(7*9)+(6*2)+(5*9)+(4*3)+(3*9)+(2*2)+(1*6)=169
169 % 10 = 9
So 92939-26-9 is a valid CAS Registry Number.

Preparations of 4-substituted 3-carboxypyrazoles
Janin, Yves L.
, p. 1410 - 1414 (2014/01/06)
The scopes of three synthetic methods reported for the preparation of an array of 3-pyrazolecarboxylates featuring substituents on position 4 were investigated. The first one is based on the potassium permanganate oxidation of methylpyrazoles. The second starts with the condensation between DMF dimethylacetal and ethyl pyruvate and is followed by the addition of hydrazine hydrochloride. The last one makes use of the cycloaddition of diazomethane on acrylate esters followed by a bromine-based oxidative rearrangement into 4-substituted 3-pyrazole esters.
