Check Digit Verification of cas no

The CAS Registry Mumber 208333-33-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,3,3 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 208333-33:
(8*2)+(7*0)+(6*8)+(5*3)+(4*3)+(3*3)+(2*3)+(1*3)=109
109 % 10 = 9
So 208333-33-9 is a valid CAS Registry Number.

Regiochemical control of a Pt-promoted alkylation of the phenyl ring

Cucciolito, Maria E.,De Renzi, Augusto,Orabona, Ida,Ruffo, Francesco,Tesauro, Diego

, p. 1675 - 1678 (2007/10/03)

The reactivity of cationic PtII-phenyl complexes of the type [PtPh(CH2=CHR)(Phen)]+ (R = H or Me) has been investigated. In all cases, insertion of the alkene into the Pt-Ph bond has been observed. The fate of the resulting Pt-CH2CHRPh (R = H or Me) derivative depends on the experimental conditions. In the presence of donor ligands (e.g. excess olefin, pyridine or triphenylphosphine) the product is stable, while in the absence of them a rapid rearrangement to form Pt-C6H4(CHRMe)-2 occurs.
