Check Digit Verification of cas no

The CAS Registry Mumber 149343-59-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,3,4 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 149343-59:
(8*1)+(7*4)+(6*9)+(5*3)+(4*4)+(3*3)+(2*5)+(1*9)=149
149 % 10 = 9
So 149343-59-9 is a valid CAS Registry Number.

INTRAMOLECULAR EXCHANGE IN TERTIARY PHOSPHINE DERIVATIVES OF DODECACARBONYLTRIOSMIUM

Deeming, Antony J.,Donovan-Mtunzi, Susan,Kabir, Shariff E.

, p. C43 - C46 (1985)

Intramolecular tertiary phosphine exchange mechanisms in the compounds 1,2- and 1,2,3-L2> (L = PMe2Ph or PPh3> have been studied by 31P and 13C NMR methods.The 13CO NMR results rule out a mechanism involving bridging carbonyl forms in favour of one involving axial-equatorial CO exchange at the same rate as phosphine exchange.
