Check Digit Verification of cas no

The CAS Registry Mumber 579476-25-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,7,9,4,7 and 6 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 579476-25:
(8*5)+(7*7)+(6*9)+(5*4)+(4*7)+(3*6)+(2*2)+(1*5)=218
218 % 10 = 8
So 579476-25-8 is a valid CAS Registry Number.

Ruthenium-Catalyzed meta-Selective CAr-H Bond Formylation of Arenes

Jia, Chunqi,Wu, Nini,Cai, Xiaofeng,Li, Gang,Zhong, Lei,Zou, Lei,Cui, Xiuling

, p. 4536 - 4542 (2020/04/09)

The meta-CAr-H bond formylation of arenes has been achieved using CHBr3 as a formyl source in the presence of [Ru(p-cym)(OAc)2] as a catalyst. This method provides efficient access to the preparation of various meta-substituted aromatic compounds, such as alcohols, ethers, amines, nitriles, alkenes, halogens, carboxylic acids, and their derivatives, through transformation of the versatile formyl group. Furthermore, mechanistic studies show that the key active species is a pentagonal ruthenacycle complex.

Cobalt-catalyzed cross-coupling between in situ prepared arylzinc halides and 2-chloropyrimidine or 2-chloropyrazine

Begouin, Jeanne-Marie,Gosmini, Corinne

supporting information; experimental part, p. 3221 - 3224 (2009/09/26)

A cobalt-catalyzed cross-coupling of aryl halides with 2-chloropyrimidines or 2-chloropyrazines is reported in satisfactory to high yields. The key step of this procedure is the formation of aromatic organozinc reagents and their coupling with 2-chlorodia
