Check Digit Verification of cas no

The CAS Registry Mumber 1263063-13-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,3,0,6 and 3 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1263063-13:
(9*1)+(8*2)+(7*6)+(6*3)+(5*0)+(4*6)+(3*3)+(2*1)+(1*3)=123
123 % 10 = 3
So 1263063-13-3 is a valid CAS Registry Number.

Synthesis of novel 4-fluoro-2H-pyrazol-3-ylamines

Cocconcelli, Giuseppe,Ghiron, Chiara,Haydar, Simon,Micco, Iolanda,Zanaletti, Riccardo

experimental part, p. 2547 - 2555 (2010/09/18)

A new and efficient synthesis for the preparation of novel 4-fluoro-2H-pyrazol-3-ylamines is described. It involves the reaction of an acyl chloride with fluoroacetonitrile and sequential ring closure of the-fluoro-ketonitrile with hydrazine. Utilizing this synthetic protocol, we have synthesized a variety of 4-fluoro-2H-pyrazol-3-ylamines with different steric and electronic demands. Taylor & Francis Group, LLC.
