Check Digit Verification of cas no

The CAS Registry Mumber 1252763-54-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,2,7,6 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1252763-54:
(9*1)+(8*2)+(7*5)+(6*2)+(5*7)+(4*6)+(3*3)+(2*5)+(1*4)=154
154 % 10 = 4
So 1252763-54-4 is a valid CAS Registry Number.

Autoxidative carbon-carbon bond formation from carbonhydrogen bonds

Pinter, Aron,Sud, Abhishek,Sureshkumar, Devarajulu,Klussmann, Martin

supporting information; experimental part, p. 5004 - 5007 (2010/09/08)

(Figure Presented) Only oxygen and acid! The oxidative coupling of xanthene and other activated benzylic compounds with carbon nucleophiles such as ketones, can be performed under ambient conditions without solvent by simply using oxygen and catalytic amounts of methanesulfonic acid. The proposed reaction mechanism involves substrate activation by formation of hydroperoxides; the method can therefore be regarded as an "autoxidative coupling reaction".
