87961-59-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 87961-59-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,6 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 87961-59:
(7*8)+(6*7)+(5*9)+(4*6)+(3*1)+(2*5)+(1*9)=189
189 % 10 = 9
So 87961-59-9 is a valid CAS Registry Number.

SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF THE ELECTRON RICH KOMPLEXES Co(η-C5Me5)(R2PCH2CH2PR2) (R = Me, Ph); PHOTOELECTRON SPECTROSCOPIC STUDIES OF SOME PENTAMETHYLCYCLOPENTADIENYLPHOSPHINECOBALT COMPLEXES

Dudeney, Nicholas,Green, Jennifer C.,Grebenik, Peter,Kirchner, Olaf N.

, p. 221 - 230 (1983)

The compounds Co(η-C5Me5)(R2PCH2CH2PR2), (R=Me, Ph) have been prepared and characterized.X-Ray diffraction studies of Co(η-C5Me5)(Me2PCH2CH2PMe2) show the two phosphorus atoms and the ring centroid to have a trigonal coordination around the cobalt.Photoelectron spectral studies show Co(η5-C5Me5)(R2PCH2CH2PR2) to have rather low first ionization energies of around 5.1 eV, indicating that the metal centre has a very electron rich nature.
