Check Digit Verification of cas no

The CAS Registry Mumber 120475-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,4,7 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 120475-66:
(8*1)+(7*2)+(6*0)+(5*4)+(4*7)+(3*5)+(2*6)+(1*6)=103
103 % 10 = 3
So 120475-66-3 is a valid CAS Registry Number.

t-butyl hydroperoxide oxidative dealkylation of hydroquinone ethers to 1,4-quinones

Wojtowicz, Halina,Mlochowski, Jacek,Syper, Ludwik,Yadav, Hardeo

, p. 1991 - 2000 (2006)

Various organoselenium compounds (diselenides, benzisoselenazol-3(2H)-ones, and 1,3,2-thiaselenazolones) are effective catalysts for oxidative dealkylation of hydroquinone ethers with t -butyl hydroperoxide to 1,4-quinones. The reactions is most efficient when t -butyl hydroperoxide in the presence of poly(bis-1,2-phenyl) diselenide is used as an oxidizing agent. In this way 1,4-benzo and 1,4-naphthoquinones are produced in good to high yields. Copyright Taylor & Francis Group, LLC.
