Check Digit Verification of cas no

The CAS Registry Mumber 1204773-50-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,4,7,7 and 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1204773-50:
(9*1)+(8*2)+(7*0)+(6*4)+(5*7)+(4*7)+(3*3)+(2*5)+(1*0)=131
131 % 10 = 1
So 1204773-50-1 is a valid CAS Registry Number.

First application of an efficient and versatile ligand for copper-catalyzed cross-coupling reactions of vinyl halides with N-heterocycles and phenols

Kabir, M. Shahjahan,Lorenz, Michael,Namjoshi, Ojas A.,Cook, James M.

supporting information; experimental part, p. 464 - 467 (2010/05/18)

[Chemical equaction presented] 2-Pyridin-2-yl-1H-benzoimidazole L3 is presented as a new, efficient, and versatile bidentate N-donor ligand suitable for the copper-catalyzed formation of vinyl C N and C O bonds. This inexpensive and easily prepared ligand facilitates copper-catalyzed cross-coupling reactions of alkenyl bromides and Iodldes with N-heterocycles and phenols to afford the desired cross-coupled products In good to excellent yields with full retention of stereochemistry. This method is particularly noteworthy given Its efficiency, that is, mild reaction conditions, low catalyst loading, simplicity, versatility, and exceptional level of functional group tolerance.
