Check Digit Verification of cas no
The CAS Registry Mumber 14282-58-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,8 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 14282-58:
(7*1)+(6*4)+(5*2)+(4*8)+(3*2)+(2*5)+(1*8)=97
97 % 10 = 7
So 14282-58-7 is a valid CAS Registry Number.

Paragraph 0059; 0064, (2018/02/28)
PROBLEM TO BE SOLVED: To provide 3,4-disubstituted thiophene sulfonate usable as a monomer for a conductive polymer, and not having carboxylate on 2,5-positions, and to provide a method for producing the same.SOLUTION: This thiophene sulfonate is represented by general formula (1). The thiophene sulfonate is obtained, for example, by decarboxylation of 3,4-dihydroxy-2,5-dicarboxylic acid thiophene in a basic inert solvent, followed by reaction with sulfonyl chlorides in the presence of a tertiary alkylamine catalyst. (In the formula, Rand Reach independently represent a 1-8C alkyl, phenyl or tolyl).
