Check Digit Verification of cas no

The CAS Registry Mumber 28232-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,2,3 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 28232-17:
(7*2)+(6*8)+(5*2)+(4*3)+(3*2)+(2*1)+(1*7)=99
99 % 10 = 9
So 28232-17-9 is a valid CAS Registry Number.

Copper-catalyzed highly regioselective 2-aryloxylation of 2,x-dihalopyridines

Zhou, Qizhong,Zhang, Bin,Du, Tieqi,Gu, Haining,Ye, Yuyuan,Jiang, Huajiang,Chen, Rener

, p. 327 - 333 (2013/01/15)

2,x-Dihalopyridines reacted with phenols catalyzed by CuI/TMEDA in the presence of Cs2CO3 in DMSO at 110 °C under nitrogen atmosphere for 24 h to afford 2-aryloxypyridines in good to high yields except p-nitrophenol. To expand this methodology, a vanilloid receptor ligand used in treatments was prepared in good yield. This method has potential utility in the synthesis of pharmaceuticals, agrochemicals and even natural products.
