310871-87-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 310871-87-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,0,8,7 and 1 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 310871-87:
(8*3)+(7*1)+(6*0)+(5*8)+(4*7)+(3*1)+(2*8)+(1*7)=125
125 % 10 = 5
So 310871-87-5 is a valid CAS Registry Number.

M(CO)6 (M = Cr, Mo, W) derivatives of (o-anisyl)diphenylphosphine, bis(o-anisyl)phenylphosphine tris(o-anisyl)phosphine and (p-anisyl)bis(o-anisyl)phosphine

Aromatic tertiary phosphine ligands having ortho-methoxy substituents reacted with Group 6 metal carbonyls to form complexes with monodentate bonding through the phosphorus atom. One tungsten hexacarbonyl derivative with two P-bonded phosphine ligands was also formed. The complexes were characterized by X-ray crystallography, 1H, 13C{1H} and 31P{1H) NMR spectroscopy, IR spectroscopy and elemental analysis. The steric properties of the ligands were studied by molecular modelling methods. Metal-phosphorus bond distances correlate with cone angles of the phosphines. (C) 2000 Elsevier Science S.A.
