Check Digit Verification of cas no
The CAS Registry Mumber 31431-18-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,4,3 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 31431-18:
(7*3)+(6*1)+(5*4)+(4*3)+(3*1)+(2*1)+(1*8)=72
72 % 10 = 2
So 31431-18-2 is a valid CAS Registry Number.

Substituted benzimidazoles. Part 2. Synthesis and properties of 2-aryl- 1-hydroxy-5-(2-thenoyl)benzimidazole 3-oxides
Kamal, Marwan R.,El-Abadelah, Mustafa M.,Mohammad, Amer A.,Meier, Herbert
, p. 819 - 832 (2007/10/03)
A selected set of 2-aryl- and 2-hetaryl-1-hydroxy-5-(2- thenoyl)benzimidazole 3-oxides (10a-m) was prepared for bioassay via condensation of the corresponding aldehydes with 4-(2-thenoyl)-1,2- benzoquinone dioxime (8) as catalyzed by perchloric acid. The dioxime (8) was obtained by facile reduction of 5-(2-thenoyl)benzofuroxan (7a) with 1,2- diphenylhydrazine. The furoxans (7a, b) are accessible by pyrolysis of the respective o-nitrophenyl azides (6a,b). Compounds (10a-g) showed a comparable range of in vitro activity against Escherichia coli and Candida albicans (MIC 62.5 - 125 μg/mL).
