54533-67-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54533-67-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,5,3 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 54533-67:
(7*5)+(6*4)+(5*5)+(4*3)+(3*3)+(2*6)+(1*7)=124
124 % 10 = 4
So 54533-67-4 is a valid CAS Registry Number.

Synthesis and spectroscopic properties of new bis-tetrazoles

Pazik, Agnieszka,Skwierawska, Anna

, p. 83 - 94 (2014/01/06)

Syntheses of N,N′-phenyltetrazole podands link with aliphatic chains containing oxygen, nitrogen and sulphur atoms, are described. The complexing properties of these compounds towards metal cations (Fe2+, Cu 2+, Zn2+, Co2+, Ni2+) were investigated by absorption and infrared spectroscopy. The UV-Vis titrations were performed to estimate the stability constant values of the respective complexes with Cu2+ ion. Changes in UV-Vis absorption spectra and IR spectra of compound 6 under various concentrations of Cu2+ ion in methanol suggest formation of very unstable complex. The structure of ligand 2 has been deduced by X-ray crystallography. The Author(s) 2012.

Studies on synthesis and infrared and fluorescence spectra of new europium and terbium complexes with an amide-based open-chain crown ether

Zhang, Yan-Ling,Qin, Wen-Wu,Liu, Wei-Sheng,Tan, Min-Yun,Tang, Ning

, p. 2153 - 2157 (2007/10/03)

An amide-based open-chain crown ether ligand and its complexes with europium and terbium were synthesized. The complexes were characterized by elemental analysis, infrared spectra and conductivity. The europium and terbium ions were found to coordinate to

SYNTHESIS OF MACROHETEROCYCLES - ANALOGS OF DIBENZO-CROWN COMPOUNDS. 2. 18-MEMBERED DIOXADIAZA-CROWN COMPOUNDS

Formanovskii, A. A.,Mikhura, I. V.,Sokolovskii, S. A.,Murakhovskaya, A. S.,Terent'ev, P. B.,Sharbatyan, P. A.

, p. 930 - 936 (2007/10/02)

Macrocyclic diamides were synthesized by condensation of bridged 1,7-bis(2-aminophenyl)-1,7-dioxaheptanes that contain an additional donor oxygen or nitrogen atom in the bridge with glutaric, diglycolic, and N-tosyliminodiacetic acid dichlorides under hig
