Check Digit Verification of cas no
The CAS Registry Mumber 28143-80-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,1,4 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28143-80:
(7*2)+(6*8)+(5*1)+(4*4)+(3*3)+(2*8)+(1*0)=108
108 % 10 = 8
So 28143-80-8 is a valid CAS Registry Number.

The oxidative addition reaction of alkylvinyl triflates with (Ph3P)4Pt and (Ph3P)2Pt(C2H4) was investigated as a prototypical example of the first step of the Ni triad metal mediated vinylic cross coupling reactions.Kinetic, stereochemical, and variable temperature NMR experiments were carried out to establish the involvement of ?-alkene complexes in these reactions.The proposed mechanism involves rate-determining formation of a ?-alkene Pt complex, followed by rapid rearrangement to a ?-vinyl triflato-Pt(II) complex, and then addition of PPh3 to yield a ?-vinylcationic Pt(II) complex.Both ?-vinyl complexes were isolated and fully characterized, as stable crystalline species.A single crystal molecular structure determination is reported for the ?-(trans-2-butenyl)tris(triphenylphosphine)platinum(II) triflate complex.
