Check Digit Verification of cas no
The CAS Registry Mumber 5744-80-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,4 and 4 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5744-80:
(6*5)+(5*7)+(4*4)+(3*4)+(2*8)+(1*0)=109
109 % 10 = 9
So 5744-80-9 is a valid CAS Registry Number.

Strategy to Prepare 3-Bromo- and 3-Chloropyrazoles
Fox, Richard J.,Schmidt, Michael A.,Eastgate, Martin D.
, p. 2830 - 2839 (2018/03/09)
A general strategy to prepare substituted 3-bromo- and 3-chloropyrazoles is described. The three-step method involves condensation of crotonates or β-chloro carboxylic acids with hydrazines, followed by halogenation and oxidation. Several condensation and oxidation protocols were developed to enable preparation of a wide variety of 3-halopyrazoles with good to excellent yields and regiocontrol.
