Check Digit Verification of cas no
The CAS Registry Mumber 112177-97-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,1,7 and 7 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 112177-97:
(8*1)+(7*1)+(6*2)+(5*1)+(4*7)+(3*7)+(2*9)+(1*7)=106
106 % 10 = 6
So 112177-97-6 is a valid CAS Registry Number.

Stereochemistry of 3-carboxylated 2,5-dihydrothiophene formation
McIntosh, John M.,Hayes, Ivy E. E.
, p. 110 - 113 (2007/10/02)
The preparation of 2-carboxylated-1,3-dienes from carbomethoxy vinylphosphonates and 2-mercaptocarbonyl compounds has been shown to give stereoisomeric mixtures.This may be due to the formation of stereoisomers of the intermediate 2,5-dihydrothiophenes an
