Check Digit Verification of cas no

The CAS Registry Mumber 2028-85-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,2 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2028-85:
(6*2)+(5*0)+(4*2)+(3*8)+(2*8)+(1*5)=65
65 % 10 = 5
So 2028-85-5 is a valid CAS Registry Number.

Synthesis and characterization of new pyrazole-based thiazoles

Abdelhamid, Abdou O.,Gomha, Sobhi M.

supporting information, p. 1409 - 1414 (2017/07/25)

A series of new 5-(heteroaryldiazenyl)thiazole incorporating pyrazole moiety have been synthesized through coupling of the thiazole with the appropriate heteroaryldiazonium salts. The newly synthesized compounds were characterized by elemental analysis, s

PROCESS FOR THE SYNTHESIS OF ARYLDIAZONIUM SALTS USING NITROGEN OXIDES IN OXYGEN-CONTAINING GAS STREAMS, ESPECIALLY FROM INDUSTRIAL WASTE GASES

Page/Page column 36; 37, (2017/06/30)

The present invention relates to a process for the synthesis of aryldiazonium salts using nitrogen oxides in oxygen-containing gas streams, especially from industrial waste gases.

Synthesis, in vitro and in Silico studies of some novel 5-nitrofuran-2-yl hydrazones as antimicrobial and antitubercular agents

Abdel-Aziz, Hatem Abdel-Kader,Eldehna, Wagdy Mohamed,Fares, Mohamed,Elsaman, Tilal,Abdel-Aziz, Marwa Mostafa,Soliman, Dalia Hussein

, p. 1617 - 1630 (2015/11/24)

In this study, we synthesized two series of novel 5-nitrofuran-2-carbohydrazides 21a-h and 22a-e in addition to a third series of thiophene-2-carbohydrazides 23a-g to develop potent antimicrobial and/or antitubercular agents. The newly synthesized compounds were evaluated in vitro for their antimicrobial and antimycobacterial activities. Most of the 5-nitrofuran-2-carbohydrazides 21a-h and 22a-e displayed variable activity against Aspergillus fumigates, Staphylococcus aureus, Streptococcus pneumonia, Bacillis subtilis, Salmonella typhimurium, Klebsiella pneumonia, Escherichia coli and Mycobacterium tuberculosis. The sulfonamide derivative 21f exhibited superior potency and broad-spectrum antimicrobial activity with minimum inhibitory concentration (MIC)=0.06-0.98 μg/mL and antimycobacterial activity with MIC=3.9 μg/mL. The 5-nitrofuran-2-carbohydrazides 21a, b, g, h and 22a-c exhibited significant antibacterial activity with MIC values in the range of 0.12-7.81 μg/mL. The significances of the 5-nitrofuran moiety and sulfonamide function were explored via the structure-activity relationship (SAR) study. In addition, docking studies revealed that the p-amino benzoic acid (PABA) and binding pockets of the dihydropteroate synthase (DHPS) were successfully occupied by compound 21f. Furthermore, two quantitative structure-activity relationship (QSAR) models were built to explore the structural requirements which controlled the activity.
