Check Digit Verification of cas no

The CAS Registry Mumber 77143-69-2 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, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 77143-69:
(7*7)+(6*7)+(5*1)+(4*4)+(3*3)+(2*6)+(1*9)=142
142 % 10 = 2
So 77143-69-2 is a valid CAS Registry Number.

Benzofuran Derivatives: Part III - Rearrangement During Cyclization of Ethyl &α-(4-Methoxycarbonylalkylphenoxy)arylacetates and Formation of 3-Aryl-2(3H)-benzofuranone-5-alkanoic Acid Esters

Shridhar, D. R.,Sastry, C. V. Reddy,Mehrotra, A. K.,Bansal, O. P.

, p. 891 - 893 (2007/10/02)

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.
