Check Digit Verification of cas no

The CAS Registry Mumber 828-81-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,2 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 828-81:
(5*8)+(4*2)+(3*8)+(2*8)+(1*1)=89
89 % 10 = 9
So 828-81-9 is a valid CAS Registry Number.

Diversity-Oriented Synthesis of 1,2,4-Triazols, 1,3,4-Thiadiazols, and 1,3,4-Selenadiazoles from N-Tosylhydrazones

Wei, Zeyang,Zhang, Qi,Tang, Meng,Zhang, Siyu,Zhang, Qian

supporting information, p. 4436 - 4440 (2021/05/26)

The diversity-oriented synthesis of 1,2,4-triazols, 1,3,4-thiadiazols, and 1,3,4-selenadiazoles from N-tosylhydrazones was developed, and the reactions were general for a wide range of substrates, in which NH2CN, KOCN, KSCN, and KSeCN were used as odorless sources. Two different pathways were proposed, and N-tosylhydrazonoyl chlorides were formed in situ in the presence of NCS.

Synthesis, docking, and biological evaluation of thiazolidinone derivatives against hepatitis C virus genotype 4a

Al-Behery, Ahmed S.,Elberembally, Kamel M.,Eldawy, Mohammed A.

, p. 1151 - 1165 (2021/04/05)

Hepatitis C virus (HCV) genotype 4a (GT4a) is prevalent in Egypt. It did not gain the necessary scientific focus despite its high resistance. Since the crystal structure NS5B (RNA-dependent RNA polymerase) of HCV GT4a has not been resolved until now, homology modeling was conducted to build and validate the 3D model of the enzyme. Ligand binding sites including the allosteric thumb II pocket were detected and used in lead optimization. Sixty new 4-thiazolidinone derivatives have been virtually designed and docked into thumb II site of HCV NS5B GT4a using rigid docking approach. Eighteen compounds (7a–r) that show good docking scores were synthesized and tested in vitro against NS5B GT4a. Compounds 7b and 7n showed the best inhibitory activity (IC50 = 0.338 and 0.342 μM, respectively). Compounds 7a, 7b, 7c, 7d, 7k, 7n, 7q, and 7r that have IC50 values less than 2 μM were assessed for cellular anti-HCV GT4a activity using human hepatoma cell line (Huh 7.5). The percentages of viral growth inhibition are between 79.67 and 94.77%. Compound 7b is the most active in the in vitro and cellular assays and could be considered a potential new lead for future anti-HCV studies. [Figure not available: see fulltext.]

Novel fatty acid-thiadiazole derivatives as potential antimycobacterial agents

Mali, Jaishree K.,Sutar, Yogesh B.,Pahelkar, Akshata R.,Verma, Preeti M.,Telvekar, Vikas N.

, p. 174 - 181 (2019/11/03)

The discovery of antibiotics around the middle twentieth century led to a decrease in the interest in antimycobacterial fatty acids. In order to re-establish the importance of naturally abundant fatty acid, a series of fatty acid-thiadiazole derivatives were designed and synthesized based on molecular hybridization approach. In vitro antimycobacterial potential was established by a screening of synthesized compounds against Mycobacterium tuberculosis H37Rv strain. Among them, compounds 5a, 5d, 5h, and 5j were the most active, with compound 5j exhibiting minimum inhibitory concentration of 2.34?μg/ml against M.tb H37Rv. Additionally, the compounds were docked to determine the probable binding interactions and understand the mechanism of action of most active molecules on enoyl-acyl carrier protein reductases (InhA), which is involved in the mycobacterium fatty acid biosynthetic pathway.

Synthesis of (1,3,4-thiadiazol-2-yl)-acrylamide derivatives as potential antitumor agents against acute leukemia cells

An, Ran,Guo, Chun,Li, Qing,Li, Yan,Wang, Renxiao,Xu, Yaochun,Zhou, Mi

supporting information, (2020/03/25)

A lead compound with the (1,3,4-thiadiazol-2-yl)-acrylamide scaffold was discovered to have significant cytotoxicity on several tumor cell lines in an in-house cell-based screening. A total of 60 derivative compounds were then synthesized and tested in a CCK-8 cell viability assay. Some of them exhibited improved cytotoxic activities. The most potent compounds had IC50 values of 1–5 μM on two acute leukemia tumor cell lines, i.e. RS4;11 and HL-60. Flow cytometry analysis of several active compounds and detection of caspase activation indicated that they induced caspase-dependent apoptosis. It was also encouraging to observe that these compounds did not have obvious cytotoxicity on normal cells, i.e. IC50 > 50 μM on HEK-293T cells. Although the molecular targets of this class of compound are yet to be revealed, our current results suggest that this class of compound represents a new possibility for developing drug candidates against acute leukemia.

An efficient one-pot synthesis of 2-amino-1,3,4-thiadiazoles from easily available aldehydes and thiosemicarbazide using TBHP as an oxidant has been described. Notably, these reactions were carried out at room temperature using ethanol as solvent. This is the first example for one-pot synthesis of 2-amino-1,3,4-thiadiazole derivatives from aldehydes. This new synthetic methodology provides a simple procedure utilizing a safer oxidizing system that affords the target products in mild reaction condition with satisfactory yields and wide substrate scope.
