Check Digit Verification of cas no

The CAS Registry Mumber 153233-06-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,2,3 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 153233-06:
(8*1)+(7*5)+(6*3)+(5*2)+(4*3)+(3*3)+(2*0)+(1*6)=98
98 % 10 = 8
So 153233-06-8 is a valid CAS Registry Number.

A highly efficient magnetic solid acid catalyst for synthesis of 2,4,5-trisubstituted imidazoles under ultrasound irradiation

Safari, Javad,Zarnegar, Zohre

, p. 740 - 746 (2013/02/22)

Fe3O4 nanoparticles were prepared by chemical coprecipitation method and subsequently coated with 3-aminopropyltriethoxysilane (APTES) via silanization reaction. Grafting of chlorosulfuric acid on the amino-functionalized Fe3O4 nanoparticles afforded sulfamic acid-functionalized magnetic nanoparticles (SA-MNPs). SA-MNPs was found to be a mild and effective solid acid catalyst for the efficient, one-pot, three-component synthesis of 2,4,5-trisubstituted imidazoles under ultrasound irradiation. This protocol afforded corresponding imidazoles in shorter reaction durations, and in high yields. This green procedure has many obvious advantages compared to those reported in the previous literatures, including avoiding the use of harmful catalysts, easy and quick isolation of the products, excellent yields, short routine, and simplicity of the methodology.

Crystal structures and solution spectroscopy of lophine derivatives

Fridman, Natalya,Kaftory, Menahem,Eichen, Yoav,Speiser, Shammai

experimental part, p. 101 - 109 (2009/04/07)

Lophine (2,4,5-triphenylimidazole) derivatives were synthesized and their physicochemical properties were determined. Spectroscopic and fluorescence behavior of lophine derivatives in methanol at different pH and various solvents were presented. The observed spectroscopic features in the solution are determined by specific interactions of the NH hydrogen. These kinds of interactions are manifested both in the solid state and in solution. The crystal and molecular structures of lophine derivatives with different solvents of crystallization are presented and discussed. In all solvates the solvent molecules link host molecules through hydrogen bonds.
