Check Digit Verification of cas no

The CAS Registry Mumber 75525-55-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,2 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 75525-55:
(7*7)+(6*5)+(5*5)+(4*2)+(3*5)+(2*5)+(1*5)=142
142 % 10 = 2
So 75525-55-2 is a valid CAS Registry Number.

Role of the trichlorostannate ligand in homogeneous catalysis. Mechanistic studies of the carbonylation of phenylpiatinum(II) complexes

Anderson, Gordon K.,Clark, Howard C.,Davies, Julian A.

, p. 64 - 70 (2008/10/08)

31P NMR studies show that the complexes trans-[Pt(SnCl3)PhL2] (L = PPh3 or PMePh2) react with carbon monoxide by an initial, rapid displacement of the trichlorostannate ligand to yield trans- [PtPh(CO)L2]+SnCl3-. Further reaction to produce trarcs-[Pt(SnCl3)(COPh)L2] occurs slowly in the absence of free CO (L = PPh3 or PMePh2) by initial nucleophilic attack of Sncl3-, but in the presence of excess CO an alternative route involving phosphine dissociation (L = PPh3 only) operates. Comparative studies with other anions have led to a reinterpretation of the role of the trichlorostannate ligand in carbonylation and decarbonylation reactions of organoplatinum(II) complexes.

Carbonylation of . New Intermediates in the CO Insertion Sequence

Anderson, Gordon K.,Cross, Ronald J.

, p. 1434 - 1438 (2007/10/02)

Phosphorus-31 n.m.r. studies of the reaction of trans- with carbon monoxide have led to the identification of several new intermediates and reaction pathways involved in the CO insertion process to produce trans-.Carbonyl addition forms a metastable five-co-ordinate compound in non-polar solvents, which eliminates a halide to form ionic species trans-X in polar solvents.Loss of PR3 from five-co-ordinate intermediates produces two isomers of which convert to the remaining isomer with Ph trans to PR3 before migration of Ph proceeds to form a benzoyl complex.A direct carbonyl insertion route from a five-co-ordinate intermediate also operates, independently of the phosphine elimination pathways, and this becomes the predominant pathways with more nucleophilic PR3 ligands.The use of elemental sulphur to remove PR3 from the reaction mixtures was instrumental in identifying some intermediates, and this method has potential synthetic value in replacing PR3 by weaker ligands at platinum.
