Check Digit Verification of cas no

The CAS Registry Mumber 1262234-34-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,2,2,3 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1262234-34:
(9*1)+(8*2)+(7*6)+(6*2)+(5*2)+(4*3)+(3*4)+(2*3)+(1*4)=123
123 % 10 = 3
So 1262234-34-3 is a valid CAS Registry Number.

Synthesis and characterization of some pyrazole derivatives of 1,5-diphenyl-1H-pyrazole-3,4-dicarboxylic acid

Kasimogullari, Rahmi,Arslan, B. Seckin

experimental part, p. 1040 - 1048 (2010/10/21)

(Chemical Equation Presented) Compound of 4-(ethoxycarbonyl)-1,5-diphenyl- 1H-pyrazole-3-carboxylic acid 2 was obtained from the reaction of ethyl 4,5-dioxo-2-phenyl-4,5-dihydrofuran-3-carboxylate and 1-benzylidene-2- phenylhydrazine. A number of substitute pyrazole dicarboxylic acid derivatives (4, 5a-c, 6, 7, 8, 9a-m, 10, 11, 12, 13, 14) were synthesized from 1,5-diphenyl-1H-pyrazole-3,4-dicarboxylic acid 3 which was prepared from basic hydrolysis of 2. Structures of synthesized compounds were characterized by 1H NMR, 13C NMR, Mass, FTIR, and elemental analysis.
