Check Digit Verification of cas no

The CAS Registry Mumber 127486-48-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,4,8 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 127486-48:
(8*1)+(7*2)+(6*7)+(5*4)+(4*8)+(3*6)+(2*4)+(1*8)=150
150 % 10 = 0
So 127486-48-0 is a valid CAS Registry Number.

An unusual base-mediated ring contraction reaction of benzopyrans to benzofurans

Buckle,Faller,Pinto,Smith

, p. 1109 - 1112 (1992)

The reaction of electron deficient pyrroles and pyrazoles with trans 3-bromo-6-cyano-3,4-dihydro-2,2-dimethyl-2H-1-benzopyran-4-ol under basic conditions results in the formation of 2-isopropylbenzofurans by a mechanism which appears to be dependent on th
