Check Digit Verification of cas no

The CAS Registry Mumber 53369-80-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,3,3,6 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 53369-80:
(7*5)+(6*3)+(5*3)+(4*6)+(3*9)+(2*8)+(1*0)=135
135 % 10 = 5
So 53369-80-5 is a valid CAS Registry Number.

Synthesis and structure of new trichloroplatinum π-complexes: Reactivity of nitrogen lone-pair versus C-C double bond π-electrons in ligands, effect of steric hindrance

Gay, Marina,Monta?a, ángel M.,Moreno, Virtudes,Font-Bardia, Mercè,Solans, Xavier

, p. 4856 - 4866 (2007/10/03)

Two trichloroplatinum π-complexes and a diammonium tetrachloroplatinate (II) salt have been unexpectedly isolated during the attempt to synthesize the corresponding cisplatinum square-planar complexes of tertiary cyclohexane 1,4-diamines. All three compounds have been physically and spectroscopically characterized, including X-ray diffraction analysis in two of the three compounds. The formation of the π-complexes instead of the diamino cis-platinum complexes could be explained as due to the steric hindrance exerted by methyl groups on the tertiary amines. So, the π-electrons of the CC double bond are more available than the electron lone pair of nitrogen atom from the amino groups. When the π-electrons of the CC from the molecule of ligand were made unavailable by transforming the cyclohexene subunit into a benzene aromatic ring, no cis-diamino dichloro platinum(II) complex nor trichloroplatinum-complexes were isolated but the corresponding tetrachloroplatinate(II) diammonium salt of the 1,4-diamino ligand.

Inclusion Compounds of Organic Onium Salts, IV. Organyl Ammonium Hosts as Versatile Clathrate Formers

Loehr, Hans-Gerd,Josel, Hans-Peter,Engel, Aloys,Voegtle, Fritz,Schuh, Willy,Puff, Heinrich

, p. 1487 - 1496 (2007/10/02)

The organyl-oligo-ammonium compounds 1 - 25 and their clathrates with a variety of low molecular weight neutral compounds, especially solvent molecules, are prepared.The inclusion capacity of the new clathrands can be explained by interstices in the host lattice.The conformational flexibility of the voluminous onium branches is responsible for the great number of clathrates; their stability depends on the ion lattice.The X-ray analysis of the ethanol clathrate of the onium host 8 shows that one ethanol molecule is surrounded by the host molecules in a cage-type manner.The great variety of the inclusions obtained up to now demonstrates that the oligo onium host compounds have to be considered as the most universal clathrands of organic chemistry.Hints are given for the syntheses of new onium clathrates.
