31237-96-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 31237-96-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,2,3 and 7 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 31237-96:
(7*3)+(6*1)+(5*2)+(4*3)+(3*7)+(2*9)+(1*6)=94
94 % 10 = 4
So 31237-96-4 is a valid CAS Registry Number.

Syntheses and Spectroscopic Investigations of Substituted cis- and trans-Dichlorobis(triphenylphospane)platinum(II) Compounds

Brune, Hans Albert,Falck, Manfred,Hemmer, Reinhard,Schmidtberg, Guenter,Alt, Helmut G.

, p. 2791 - 2802 (2007/10/02)

Compounds of the type cis- and trans-dichlorobis(triphenylphosphane)platinum(II) (3) with substituents of different electronic character in the phenyl rings bonded to phosphorus have been synthesized.The coupling constants 1J and the chloro-platinum valence vibrational frequencies are demonstrated to be criteria for unambiguous discrimination between cis- and trans-configurations at platinum; a linear correlation exists between the sum of the ?-constants of the sustituents at the triphenylphosphane and the coupling constants 1J.
