153588-53-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 153588-53-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,5,8 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 153588-53:
(8*1)+(7*5)+(6*3)+(5*5)+(4*8)+(3*8)+(2*5)+(1*3)=155
155 % 10 = 5
So 153588-53-5 is a valid CAS Registry Number.

Evidence on Ligand Strengths from the Crystal Structures of , , 2>*PhCHO and from Dimethylformamide (dmf), Dimethylacetamide (dma), Benzaldehyde and Acetophenone

Jin, Songchun,McKee, Vickie,Nieuwenhuyzen, Mark,Robinson, Ward T.,Wilkins, Cuthbert J.

, p. 3111 - 3116 (1993)

X-Ray crystal structure determinations have been made for the fac octahedral complexes 1, 2 and 2>*PhCHO 3, from dimethylformamide (dmf), dimethylacetamide and benzaldehyde and the trigonal-bipyramidal complex 4 from acetophenone.The average In-O bond length for 3 is ca. 0.07 Angstroem greater than for 1 or 2.In 4, In-O is 0.07 Angstroem longer than that known for from tetramethylurea (tmu).An extension of the comparison to structures involving other ligands shows there to be a general correspondence between In-O bond lengths and ligand donor values.By contrast with the weak co-ordination of aldehydes and ketones, co-ordination of an amide is enhanced through polarisation.In the crystal of 3, individual molecules are paired, almost centrosymmetrically, with intermeshing of their PhCHO ligands.
