Check Digit Verification of cas no

The CAS Registry Mumber 1206200-26-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,6,2,0 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1206200-26:
(9*1)+(8*2)+(7*0)+(6*6)+(5*2)+(4*0)+(3*0)+(2*2)+(1*6)=81
81 % 10 = 1
So 1206200-26-1 is a valid CAS Registry Number.

Copper-catalyzed annulation of 2-formylazoles with o-aminoiodoarenes

Reeves, Jonathan T.,Fandrick, Daniel R.,Tan, Zhulin,Song, Jinhua J.,Lee, Heewon,Yee, Nathan K.,Senanayake, Chris H.

, p. 992 - 994 (2010)

(Chemical Equation Presented) In the presence of catalytic CuI and sparteine, 2-formylpyrroles can be annulated with o-aminoiodoarenes to give substituted pyrrolo[1,2-a]quinoxalines and related heterocycles. The reaction also works for annulation of 2-formylindoles, 2-formylimidazole, 2-formylbenzimidazole, and a 3-formylpyrazole.
