95870-54-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 95870-54-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,5,8,7 and 0 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 95870-54:
(7*9)+(6*5)+(5*8)+(4*7)+(3*0)+(2*5)+(1*4)=175
175 % 10 = 5
So 95870-54-5 is a valid CAS Registry Number.

Two new methods to form substituted oligoethylene glycols

Krakowiak, Krzysztof E.,Bradshaw, Jerald S.,Huszthy, Peter

, p. 2853 - 2856 (1994)

1-Bromo-2-trityloxyethane (1) and 1-allyloxymethyl-2-trityloxyethanol (2) react readily at room temperature with substituted oligoethylene glycols or the ditosylate derivative of an oligoethylene glycol, respectively, to form the extended, ditrityl-protected, substituted oligoethylene glycols in high yields. The trityl groups are easily removed by acidified methanol in CH2Cl2 to give the extended, substituted oligoethylene glycols.

2,2'-Bipyridine lariat calixcrowns: A new class of encapsulating ligands forming highly luminescent Eu3+ and Tb 3+ complexes

Fischer, Claudia,Sarti, Gianluca,Casnati, Alessandro,Carrettoni, Barbara,Manet, Ilse,Schuurman, Ruud,Guardigli, Massimo,Sabbatini, Nanda,Ungaro, Rocco

, p. 1026 - 1034 (2007/10/03)

A new class of calix[4]arene crown ethers with one or two bipyridines appended to the polyether ring (lariat calixcrowns) have been designed and synthesized; the luminescence properties of their Eu3+ and Tb3+ complexes have been studied in acetonitrile. In this solvent, long lifetimes for the metal emitting states and high metal-luminescence intensities obtained upon ligand excitation have been observed in both Eu3+ and Tb3+ complexes. The association constants in methanol have been determined for some of the complexes studied.
