127087-67-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127087-67-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,8 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127087-67:
(8*1)+(7*2)+(6*7)+(5*0)+(4*8)+(3*7)+(2*6)+(1*7)=136
136 % 10 = 6
So 127087-67-6 is a valid CAS Registry Number.

A new efficient tetraphosphine/palladium catalyst for the Heck reaction of aryl halides with styrene or vinylether derivatives

Feuerstein, Marie,Doucet, Henri,Santelli, Maurice

, p. 2191 - 2194 (2002)

cis,cis,cis-1,2,3,4-Tetrakis(diphenylphosphinomethyl)cyclopentane/[PdCl(C 3H5)]2 system efficiently catalyses the Heck reaction of aryl halides with styrene and vinylether derivatives. High turnover numbers can be obtained for the reaction of several aryl halides with styrene and styrene derivatives. Lower turnover numbers have been observed in the presence of vinylethers.

1,10-Phenanthroline Derivatives: A New Ligand Class in the Heck Reaction. Mechanistic Aspects

Cabri, Walter,Candiani, Ilaria,Bedeschi, Angelo,Santi, Roberto

, p. 7421 - 7426 (2007/10/02)

Mechanistic studies concerning the use of 1,10-phenanthroline derivatives as palladium ligands in the Heck reaction are described.The work is focused on the steering factors for the coordination of unsaturated systems onto palladium(0) and palladium(II) complexes.
