2028-84-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2028-84-4 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 4 respectively.
Calculate Digit Verification of CAS Registry Number 2028-84:
(6*2)+(5*0)+(4*2)+(3*8)+(2*8)+(1*4)=64
64 % 10 = 4
So 2028-84-4 is a valid CAS Registry Number.

Ultrasound Assisted Synthesis of Some Novel Bis-Pyridazine Derivatives

Mekky, Ahmed E. M.,Al-Bogami, Abdullah S.

, p. 595 - 605 (2016)

Bis-enaminone 3 was coupled with aryldiazonium chlorides 4a, 4b to afford the bis-arylhydrazonopropanals 6a, 6b. Compounds 6a, 6b could be utilized for the synthesis of a variety of bis-(dimethyl 2,3-dihydropyridazine-3,4-dicarboxylate), bis-(pyridazin-3(

Novel method for the synthesis of 6,12-dihydro-2-methylindolo[2,3- b]carbazol-6-ones

Ebenezer Martin,Prasad, K. J. Rajendra

, p. 1778 - 1783 (2008)

A novel method for the synthesis of 6,12-dihydro-2-methylindolo[2,3-b] carbazol-6-ones was developed from 1-oxo-2,3,4,9-tetrahydro-1H-carbazol-1-one through methyl 6-methyl-2-(1-oxo-2,3,4,9-tetrahydro-1H-carbazol-2-yl)oxoacetate in good yields. This metho

Synthesis and antioxidant assay of new nicotinonitrile analogues clubbed thiazole, pyrazole and/or pyridine ring systems

Abumelha, Hana M. A.

, (2020/01/21)

A series of novel nicotinonitrile derivatives were synthesized by hybridization with thiazole, pyrazole, and pyridine ring systems using 4-aminobenzohydrazide as link-bridge. The synthetic strategy of nicotinonitrile-thiazole analogues involves cyclizatio

New Thiophene Derivatives as Antimicrobial Agents

Mabkhot, Yahia Nasser,Kaal, Nahed Ahmed,Alterary, Seham,Mubarak, Mohammad S.,Alsayari, Abdulrhman,Bin Muhsinah, Abdullatif

, p. 2845 - 2953 (2019/08/26)

Phenacylbromide derivatives constitute a multilateral group of precursors for the synthesis of numerous heterocycles of organic compounds. Briefly, 5-(2-bromo-acetyl)-substituted-thiophene derivative has been used as a synthon for synthesis of new thiophene-containing compounds through the reaction with nucleophilic nitrogen compounds and thioamides. The suggested structures of the newly synthesized thiophene compounds were confirmed and assured with different spectroscopic tools and with CHN elemental analysis. Additionally, the antimicrobial activity of these thiophene compounds was recorded to investigate their potency against various types of bacteria and fungi. Results showed that these compounds exhibit significant inhibitory activity against the growth of tested bacterial and fungal strains and that some derivatives were more potent than the employed reference drugs.
