38720-22-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 38720-22-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,7,2 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 38720-22:
(7*3)+(6*8)+(5*7)+(4*2)+(3*0)+(2*2)+(1*2)=118
118 % 10 = 8
So 38720-22-8 is a valid CAS Registry Number.

Resolution of 4-benzylideneacetone)Fe(CO)3>. Structure and configurational stability of *> (L* = (+)-neomenthyldiphenylphosphine

Marcuzzi, A.,Linden, A.,Rentsch, D.,Philipsborn, W. von

, p. 87 - 97 (2007/10/02)

Resolution of 4-benzylideneacetone)Fe(CO)3> has been achieved by (reversible) thermal displacement of a CO ligand by use of the chiral phosphine (+)-neomenthyldiphenylphosphine ((+)-NMDPP).The two diastereomers formed were separated by chromatography and treated with carbon-monoxide to give the corresponding optically active Fe(CO)3 complexes.The circular dichroism spectra are discussed.The absolute configuration of the planar chirality element in the two diastereomers has been determined by an X-ray diffraction study.
