57681-56-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 57681-56-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,7,6,8 and 1 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 57681-56:
(7*5)+(6*7)+(5*6)+(4*8)+(3*1)+(2*5)+(1*6)=158
158 % 10 = 8
So 57681-56-8 is a valid CAS Registry Number.

The demethylation of 2-methoxy-3-(2-pyridyl)thiophene with chlrotrimethylsilane-sodium iodide in refluxing acetonitrile or with boron tribromide in dichloromethane at ambient temperature led to the formation of (+/-)-(3R*, 4S*)-3-(2-pyridyl)-4--4,5-dihydrothiophen-2(3H)-one.A possible mechanism by which the compound is formed is proposed.The structure of the compound has been established by X-ray crystallography.
