Check Digit Verification of cas no

The CAS Registry Mumber 1280211-57-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,2,1 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1280211-57:
(9*1)+(8*2)+(7*8)+(6*0)+(5*2)+(4*1)+(3*1)+(2*5)+(1*7)=115
115 % 10 = 5
So 1280211-57-5 is a valid CAS Registry Number.

Copper(I) Phenoxide complexes in the etherification of aryl halides

Tye, Jesse W.,Weng, Zhiqiang,Giri, Ramesh,Hartwig, John F.

, p. 2185 - 2189 (2010)

"Chemical Equation Presented" No copping out! Copper(I) phenoxide complexes containing chelating ligands (see picture), proposed intermediates in copper-catalyzed etherification of aryl halides, have been synthesized and fully characterized. The kinetic and chemical competence of the isolated complexes are demonstrated for the synthesis of aryl phenyl ethers, and experiments provide evidence against mechanistic pathways involving the formation of either free or caged radicals.
