Check Digit Verification of cas no

The CAS Registry Mumber 1216910-68-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,6,9,1 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1216910-68:
(9*1)+(8*2)+(7*1)+(6*6)+(5*9)+(4*1)+(3*0)+(2*6)+(1*8)=137
137 % 10 = 7
So 1216910-68-7 is a valid CAS Registry Number.

Palladium-catalyzed direct benzylation of azoles with benzyl carbonates

Mukai, Tomoya,Hirano, Koji,Satoh, Tetsuya,Miura, Masahiro

supporting information; experimental part, p. 1360 - 1363 (2010/05/19)

"Chemical Equation Presented" The direct aromatic sp2 C-H benzylation of azole compounds with benzyl carbonates proceeds efficiently in the presence of a Pd2(dba)3/dppp catalyst system and KaOAc as a base to afford the corresponding diarylmethanes in good yields. In addition, the same palladium catalyst enables the direct benzylic sp3 C-H benzylation with the second benzyl carbonates without employing any external base.
