Check Digit Verification of cas no
The CAS Registry Mumber 400755-43-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,0,0,7,5 and 5 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 400755-43:
(8*4)+(7*0)+(6*0)+(5*7)+(4*5)+(3*5)+(2*4)+(1*3)=113
113 % 10 = 3
So 400755-43-3 is a valid CAS Registry Number.

Electrosynthesis of 4-chloropyrazolecarboxylic acids
Lyalin,Petrosyan,Ugrak
experimental part, p. 291 - 296 (2010/07/09)
4-Chlorosubstituted pyrazolecarboxylic acids were synthesized via chlorination of the corresponding acids at the Pt anode in NaCl aqueous solutions under conditions of divided galvanostatic electrolysis. The efficiency of the process depends on the structures of the initial pyrazolecarboxylic acids, particularly, on the donor-acceptor properties of the substituents and on their position in the pyrazole ring. The yields of the 4-chlorosubstituted products of chlorination of pyrazole-3(5)-carboxylic acid, 1-methylpyrazole-5- carboxylic acid, 1-methyl-pyrazole-3-carboxylic acid, 1-ethylpyrazole-3- carboxylic acid, and 1-methyl-3-nitropyrazole- 5-carboxylic acid are 92, 93, 69, 80, and 4%, respectively.
