Check Digit Verification of cas no

The CAS Registry Mumber 98508-66-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,5,0 and 8 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 98508-66:
(7*9)+(6*8)+(5*5)+(4*0)+(3*8)+(2*6)+(1*6)=178
178 % 10 = 8
So 98508-66-8 is a valid CAS Registry Number.

SYNTHESIS OF 4-CARBOXY-2-THIABICYCLOHEPTAN-6-ONES VIA 3-CARBOXY-2,3-DIHYDROTHIOPHENES: POTENTIAL β-LACTAMASE INHIBITORS

Lange, Gerald,Savard, Marc E.,Viswanatha, Thammaiah,Dmitrienko, Gary I.

, p. 1791 - 1794 (1985)

3-Carboalkoxy-2,3-dihydrothiophenes, available by Birch reduction of thiophene-3-carboxylic acid or more efficiently by deconjugation of 2,5-dihydrothiophene-3-carboxylic acid by reaction with ethyl chloroformate and triethylamine, undergo cycloaddition reactions with dichloroketene leading to 4-carboxy-7,7-dichloro-2-thiabicycloheptan-6-ones which are of interest as potential β-lactamase inhibitors.
