Check Digit Verification of cas no

The CAS Registry Mumber 609769-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,9,7,6 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 609769-99:
(8*6)+(7*0)+(6*9)+(5*7)+(4*6)+(3*9)+(2*9)+(1*9)=215
215 % 10 = 5
So 609769-99-5 is a valid CAS Registry Number.

Palladium(II) complexes containing a pyridinyliminophosphorane ligand

Wu, Hung-Ren,Liu, Yi-Hung,Peng, Shie-Ming,Liu, Shiuh-Tzung

, p. 3152 - 3159 (2007/10/03)

A series of new pyridinyliminophosphorane bidentate ligands with different steric environments [(2-C6H4N)PPh2= NAr (NPN)] and their methylpalladium complexes PdClMe(NPN)] were prepared. From the crystal structure analysis it is evident that the alkyl ligands are always trans to the pyridinyl nitrogen donor, revealing a σ-donating ability of the iminophosphorane. However, the two Pd-Cl bonds in [PdCl2(NPN)] are essentially the same length. Cationic palladium complexes catalyzed the copolymerization of norbornene/ethylene as well as CO/norbornene.
