800-67-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 800-67-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,0 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 800-67:
(5*8)+(4*0)+(3*0)+(2*6)+(1*7)=59
59 % 10 = 9
So 800-67-9 is a valid CAS Registry Number.

Nickel-catalyzed cross-coupling reaction of alkenyl methyl ethers with aryl boronic esters

Shimasaki, Toshiaki,Konno, Yuko,Tobisu, Mamoru,Chatani, Naoto

supporting information; experimental part, p. 4890 - 4892 (2010/01/06)

The Ni(0)-catalyzed cross-coupling of alkenyl methyl ethers with boronic esters is described. Several types of alkenyl methyl ethers can be coupled with a wide range of boronic esters to give the stilbene derivatives.

Synthesis of polysubstituted alkenes by Heck vinylation or Suzuki cross-coupling reactions in the presence of a tetraphosphane-palladium catalyst

Berthiol, Florian,Doucet, Henri,Santelli, Maurice

, p. 1091 - 1096 (2007/10/03)

Through the use of [PdCl(C3H5)]2/cis,cis,cis-1,2,3, 4-tetrakis[(diphenylphosphanyl)methyl]cyclopentane as a catalyst, a range of vinyl bromides undergo Suzuki cross-couplings with arylboronic acids in good yields. Furthermore, the catalyst can be used at low loadings, even for reactions of sterically hindered substrates. Mediated by this catalyst, stilbene and 1,1-diphenylethylene undergo Heck reactions with aryl halides to give triarylethylene derivatives. Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003.
