Check Digit Verification of cas no

The CAS Registry Mumber 255837-19-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,5,8,3 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 255837-19:
(8*2)+(7*5)+(6*5)+(5*8)+(4*3)+(3*7)+(2*1)+(1*9)=165
165 % 10 = 5
So 255837-19-5 is a valid CAS Registry Number.

Synthesis of di-tert-butylphenol [...] biphenyl compounds (by machine translation)

-

Paragraph 0014, (2019/03/06)

The invention discloses a method for synthesizing tert-[...] biphenyl compounds, which belongs to the field of organic synthesis. In the oxygen free atmosphere, in order to di-tert-butylphenol [...] as raw material, under the action of the palladium catalyst, with the O-bromophenylacetic reaction, then the obtained by coupling with aryl boric acid di-tert-butylphenol [...] biphenyl compound. Compared with the prior art the invention less reaction steps, the operation is simple, high yield, is more suitable for industrial production. (by machine translation)

Highly active and selective catalysts for the formation of α-aryl ketones

Fox, Joseph M.,Huang, Xiaohua,Chieffi, Andre,Buchwald, Stephen L.

, p. 1360 - 1370 (2007/10/03)

Bulky, electron-rich phosphine ligands with a biphenyl backbone, when combined with Pd(OAc)2, give highly active catalysts for the α-arylation of ketones. The ligand 2-methyl-2'-dicyclohexylphosphinobiphenyl is particularly effective, and with
