Check Digit Verification of cas no
The CAS Registry Mumber 77143-72-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,4 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77143-72:
(7*7)+(6*7)+(5*1)+(4*4)+(3*3)+(2*7)+(1*2)=137
137 % 10 = 7
So 77143-72-7 is a valid CAS Registry Number.

Treatment of ethyl α-(4-methoxycarbonylalkylphenoxy)arylacetates (III) with conc.H2SO4 or PPA leads to 3-aryl-2(3H)-benzofuranone-5-alkanoic acid esters (V), via rearrangement and cyclization.Acid hydrolysis of V furnishes 3-aryl-2(3H)-benzofuranone-5-alkanoic acids (VI).These compounds show a moderate antiinflammatory activity.
