Check Digit Verification of cas no

The CAS Registry Mumber 159685-77-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,6,8 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 159685-77:
(8*1)+(7*5)+(6*9)+(5*6)+(4*8)+(3*5)+(2*7)+(1*7)=195
195 % 10 = 5
So 159685-77-5 is a valid CAS Registry Number.

Ultrasonic-assisted preparation of Co3O4 and Eu-doped Co3O4 nanocatalysts and their application for solvent-free synthesis of 2-amino-4H-benzochromenes under microwave irradiation

Kafi-Ahmadi, Leila,Poursattar Marjani, Ahmad,Nozad, Ehsan

, (2021/05/10)

Co3O4 and Eu-doped Co3O4 nanocatalysts were synthesized through an ultrasonic-assisted solvothermal method and were characterized with X-ray diffraction (XRD), Fourier transform infrared (FT-IR), energy-dispersi

Abstract: GO-Fc@Fe3O4 nanohybrid as a powerful and reusable nanocatalyst was synthesized. The graphene oxide (GO) sheets with meta-chloroperoxybenzoic acid (mCPBA) were treatment, afterward were chemically modified with 4-Fc derivati

Synthesis and characterization of a novel Fe3O4@SiO2-BenzIm-Fc[Cl]/BiOCl nano-composite and its efficient catalytic activity in the ultrasound-assisted synthesis of diverse chromene analogs

In this study, a novel magnetically recoverable Fe3O4@SiO2-BenzIm-Fc[Cl]/BiOCl nano-composite was synthesized using a simple chemical co-precipitation method. This is the first time that a magnetic nano-catalyst bearing ionic liquid, ferrocene and BiOCl is synthesized. The Fe3O4@SiO2-BenzIm-Fc[Cl]/BiOCl nano-composite was characterized by Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX) and field emission scanning electron microscopy (FE-SEM) techniques. The catalytic activities of the novel magnetic nano-composite were evaluated in one-pot three-component synthesis of a wide variety of 2-amino-3-cyano-4H-chromene derivatives under ultrasound irradiation. A simple, facile and highly efficient ultrasound-assisted method was developed to synthesize 4H-chromene derivatives via one-pot, three-component reaction of aldehyde, malononitrile and active phenolic compounds (2-naphthol, 1-naphthol, 3-(dimethylamino)phenol, resorcinol and orcinol) at room temperature. The reaction of aldehyde, malononitrile and orcinol is newly introduced in this paper. The ultrasound-assisted synthesis protocol that was studied in this article exhibits some notable advantages such as short reaction times, operational simplicity, green reaction conditions, high yields and easy work-up and purification steps. In addition, the novel magnetic nano-composite could be easily recovered by an external magnetic field and reused for six-reaction cycles without significant loss of its catalytic activity.
