Check Digit Verification of cas no

The CAS Registry Mumber 598-81-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,9 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 598-81:
(5*5)+(4*9)+(3*8)+(2*8)+(1*1)=102
102 % 10 = 2
So 598-81-2 is a valid CAS Registry Number.

Unusual ammonolysis of a secondary amide assisted by unsubstituted vicinal amide group

Arcelli, Antonio,Porzi, Gianni,Sandri, Sergio

, p. 4141 - 4148 (1996)

Evidence for the participation of neighboring -CONH2 group in the ammonolysis of disubstituted amide was obtained. The surprising conversion of 1 into 3 in very mild conditions is a process formed by two consecutive first order reactions. Kinetics were performed in ethanol at various temperatures and NH3 concentrations. The ammonolysis of the isolated intermediate 2 allowed the unambiguous attribution of k1 and k2 to steps 1 → 2 and 2 → 3, respectively. The thermodynamic parameters of activation for both steps of the process were evaluated.

Highly Efficient Synthesis of Amino Acids by Amination of Bio-Derived Hydroxy Acids with Ammonia over Ru Supported on N-Doped Carbon Nanotubes

Xie, Zhenbing,Chen, Bingfeng,Peng, Fangfang,Liu, Mingyang,Liu, Huizhen,Yang, Guanying,Han, Buxing

, p. 5683 - 5689 (2020/09/21)

The amino acids have extensive applications, and their productions from biomass-derived feedstocks are very attractive. In this work, the synthesis of amino acids by amination of bio-derived hydroxy acids with ammonia over different metallic nano-catalysts supported on various supports is studied. It is found that Ru nano-catalysts on the nitrogen-doped carbon nanotubes (Ru/N?CNTs) have an outstanding performance for the reaction. Different hydroxy acids can be catalytically converted into the corresponding amino acids with yields up to 70.0 % under mild conditions, which is higher than those reported. The reasons for the high efficiency of the catalyst are investigated, and the reaction pathway is proposed on the basis of control experiments.

Promotion of catalytic properties of vanillin loaded MCM-41 by Cu(I) and Cu(II) for enhanced removal of quinoline contaminants

Arjmand, Mehdi,Fazaeli, Reza,Ghorbani, Mohammad Hossein,Kamani, Mina

, p. 4833 - 4841 (2020/09/16)

In the present study, to enhance removal of quinoline contaminants using natural active component, vanillin was loaded onto the MCM-41 (Mobile Component Material) nanoparticles in a simple way. The product was divided into two parts, which were improved by Copper(I) and Copper(II) salts. Promoted synthetic nanocatalysts (Cu(I)/Van./MCM-41, and Cu(II)/Van./MCM-41) were characterized using X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Energy-Dispersive X-Ray Spectroscopy (EDS), Mapping, Fourier-Transform Infrared Spectroscopy (FTIR), and BET/BJH (Brunauer-Emmett-Teller (BET) and Barret-Joyner-Halenda (BJH)) techniques. To reach optimal conditions, experimental design was performed using Response Surface Methodology (RSM). The experiments were done with the aid of nanocomposites, in presence of ultraviolet radiation without any auxiliary oxidants. Degradation percentages were measured by an Ultraviolet (UV) spectrophotometer. The products were identified using Gas Chromatography–Mass (GC-Mass) technique, and some mechanisms for quinoline removal were proposed. The results indicated that Cu (I) showed better performance in enhanced removal of quinoline than Cu(II).
