Check Digit Verification of cas no

The CAS Registry Mumber 1078738-57-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,7,8,7,3 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1078738-57:
(9*1)+(8*0)+(7*7)+(6*8)+(5*7)+(4*3)+(3*8)+(2*5)+(1*7)=194
194 % 10 = 4
So 1078738-57-4 is a valid CAS Registry Number.

A general method for copper-catalyzed arylation of arene C-H bonds

Do, Hien-Quang,Khan, Rana M. Kashif,Daugulis, Olafs

, p. 15185 - 15192 (2008)

A general method for copper-catalyzed arylation of sp2 C-H bonds with pKa's below 35 has been developed. The method employs aryl halide as the coupling partner, lithium alkoxide or K3PO4 base, and DMF, DMPU, or mixed DMF/xylenes solvent. A variety of electron-rich and electron-poor heterocycles such as azoles, caffeine, thiophenes, benzofuran, pyridine oxides, pyridazine, and pyrimidine can be arylated. Furthermore, electron-poor arenes possessing at least two electron-withdrawing groups on a benzene ring can also be arylated. Two arylcopper-phenanthroline complex intermediates were independently synthesized.
