Check Digit Verification of cas no

The CAS Registry Mumber 204199-23-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,4,1,9 and 9 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 204199-23:
(8*2)+(7*0)+(6*4)+(5*1)+(4*9)+(3*9)+(2*2)+(1*3)=115
115 % 10 = 5
So 204199-23-5 is a valid CAS Registry Number.

Photochemische Untersuchungen an Bis(phenyl)(diarsan)platin(II)-Verbindungen

Brune, Hans-Albert,Klotzbuecher, Rainer,Schmidtberg, Guenther

, p. 389 - 402 (1989)

The compounds (η2-diarsane)bis(phenyl)platinum(II) with either a CH3, (CH3)2CH, (CH3)3C, F, Br, CF3, (CH3)3Si in the 4-position of the platinum-bound phenyl rings have been synthesized and studied photochemically.After excitation into the longest wavelength absorption band they eliminate the two substituted, platinum-bound rings as a biphenyl, but are photo-stable when excited by shorter wavelength UV-radiation.The elimination is exclusively intramolecular and stereospecific; it is an example of a concerted pericyclic at a transition metal.
