Check Digit Verification of cas no

The CAS Registry Mumber 7158-91-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,5 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7158-91:
(6*7)+(5*1)+(4*5)+(3*8)+(2*9)+(1*1)=110
110 % 10 = 0
So 7158-91-0 is a valid CAS Registry Number.

Palladium-catalyzed C-O bond formation: direct synthesis of phenols and aryl/alkyl ethers from activated aryl halides

Chen, Guoshu,Chan, Albert S.C.,Kwong, Fuk Yee

, p. 473 - 476 (2008/02/03)

A simple and efficient palladium-catalyzed carbon-oxygen bond formation is reported. The palladium-tri-tert-butylphosphine complex was found to be effective in converting haloarenes to corresponding substituted phenols. This methodology offers a direct transformation of aryl halides to phenols, as well as the straightforward application to generate a wide variety of diaryl or alkyl/aryl ethers.

The nitration of electron-rich aromatics

Dwyer,Holzapfel

, p. 7843 - 7848 (2007/10/03)

The successful mononitration of a variety of electron-rich aromatic substrates is reported, employing either nitronium tetrafluoroborate or 'claycop' as the nitrating agent. Dinitration of four of the substrates was achieved when employing nitronium tetrafluoroborate. Several of the products have previously been prepared only by indirect methods.
