67488-51-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 67488-51-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,4,8 and 8 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 67488-51:
(7*6)+(6*7)+(5*4)+(4*8)+(3*8)+(2*5)+(1*1)=171
171 % 10 = 1
So 67488-51-1 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
