Check Digit Verification of cas no

The CAS Registry Mumber 1220099-84-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,0,0,9 and 9 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1220099-84:
(9*1)+(8*2)+(7*2)+(6*0)+(5*0)+(4*9)+(3*9)+(2*8)+(1*4)=122
122 % 10 = 2
So 1220099-84-2 is a valid CAS Registry Number.

Copper(II)-catalyzed ortho-acyloxylation of the 2-arylpyridines sp 2 C-H bonds with anhydrides, using O2 as terminal oxidant

Wang, Wenhui,Luo, Fang,Zhang, Shouhui,Cheng, Jiang

supporting information; experimental part, p. 2415 - 2418 (2010/06/16)

(Figure Presented) A chelation-assisted copper(II)-catalyzed ortho-acyloxylation of the 2-arylpyridine sp2 C-H bond with anhydride is described. The procedure tolerates various functional groups, such as carbomethoxyl, methoxyl, fluoro, bromo, chloro, and cyano groups, affording the mono- or diacyloxylated products in moderate to good yields. Importantly, this procedure uses O2 as a clean terminal oxidant.
