Check Digit Verification of cas no

The CAS Registry Mumber 207393-28-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,7,3,9 and 3 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 207393-28:
(8*2)+(7*0)+(6*7)+(5*3)+(4*9)+(3*3)+(2*2)+(1*8)=130
130 % 10 = 0
So 207393-28-0 is a valid CAS Registry Number.

3,5-dichlorotrifluorophenyl complexes, aryl derivatives with simple 19F NMR structural probes. The synthesis of general precursors for Pd- and Pt complexes

Espinet, Pablo,Martinez-Ilarduya, Jesus M.,Perez-Briso, Celeste,Casado, Arturo L.,Alonso, M. Aranzazu

, p. 9 - 20 (2007/10/03)

High yield methods for the synthesis of cis-[MR2(COD)] (M=Pd, Pt; R=3,5-C6Cl2F3), cis-[MR2(THF)2] (M=Pd; Pt), trans-[PdR2L2] (L=tht; SMe2), trans-[PtR2(SMe2)2], and [M2(μ-Cl)2R2L2] (M=Pd, L=NCPh, tht, SMe2; M=Pt, L=tht) are reported. These complexes are general precursors for the preparation of other complexes containing cis-MR2, trans-MR2 and MClR moieties in almost quantitative yields. Thus, by displacement of COD, THF, tht or SMe2 by other ligands, almost any isomer of any complex with one or two aryl rings can be prepared. The 19F NMR spectra of these complexes are simple compared to those of other polyfluorophenyl groups, and some examples of the spectral advantages of this partially fluorinated ligand are given.
