Check Digit Verification of cas no

The CAS Registry Mumber 141239-38-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,2,3 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 141239-38:
(8*1)+(7*4)+(6*1)+(5*2)+(4*3)+(3*9)+(2*3)+(1*8)=105
105 % 10 = 5
So 141239-38-5 is a valid CAS Registry Number.

Nucleophilic attack by 2-pyridylpalladium(II) and platinum(II) complexes on the organic chlorides ClCH2R (R = COMe, CN, Ph, Cl)

Crociani, Bruno,Bianca, Francesca Di,Fontana, Alberta,Bertani, Roberta

, p. 155 - 164 (2007/10/02)

The 2-pyridyl complexes trans-2)(PPh3)2> (M = Pd, 1a; M = Pt, 1b), 2)(dppe)> (M = Pd, 2a; M = Pt, 2b) and 2)(PPh3)> (M = Pd, 3a; M = Pt, 3b) react with the chlorides ClCH2R (R = COMe, CN, Ph) to give cationic products containing the 2-pyridylium ligands (1-CH2R)C5H4N-C2.The rate of nucleophilic displacement of the chloride ion from ClCH2R depends on the central metal (Pt > Pd), on the coordination geometry (1 CN > Ph for the reactions with 3b).Like 1b and 2b, complex 3b also reacts with dichloromethane to give 2>(PPh3)>+.The reaction of the binuclear compound 2,N)(PPh3)>2> with chloroacetone in the presence of chloride ion yields the zwitterionic derivative cis-2>(PPh3)>.The cationic products have been isolated and characterized as perchlorate salts.
