Check Digit Verification of cas no

The CAS Registry Mumber 24398-88-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,3,9 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 24398-88:
(7*2)+(6*4)+(5*3)+(4*9)+(3*8)+(2*8)+(1*8)=137
137 % 10 = 7
So 24398-88-7 is a valid CAS Registry Number.

Theoretical and computational insight into the supramolecular assemblies of Schiff bases involving hydrogen bonding and C[sbnd]H…π interactions: Synthesis, X-ray characterization, Hirshfeld surface analysis, anticancer activity and molecular docking analysis

The present study examines the significance of various non-covalent interactions in the supramolecular assembly of (E)-1-(1-(4-nitrophenyl)ethylidene)-2-phenylhydrazine 1c and (E)-3?bromo-N'-(1-phenylethylidene)benzohydrazide 2d. The synthesized compounds were fully characterized by spectroscopic methods and single crystal X-ray diffraction analysis. The topology of the supramolecular assemblies was controlled by various non-covalent interactions including classical hydrogen bonding, C[sbnd]H…π and Br…Br interactions which were examined in detail using several theoretical methods and DFT calculations. The optimized geometric parameters of compounds 1c and 2d were calculated using density functional theory (DFT/B3LYP) quantum chemical method with the 6–311++G(d,p) basis set using the crystallographic coordinates. Additionally, fragments contributing to the HOMO and LUMO molecular orbitals were investigated at the same level of theory. The nature and various types of intermolecular interactions in the crystal structures was also investigated by Hirshfeld surface analysis. The synthesized Schiff bases were also studied for their potential as drugs and physicochemical properties. Bioevaluation against four cancer cell lines (NCI-H460, NCI-H460/Bcl-2, MDA-MB-231 and MCF-7) showed that compound 1c was a more potent inducer of toxicity compared to 2d. The putative binding modes of the bioactive Schiff bases were investigated using molecular docking tools and the results revealed that both the inhibitors were stabilized in the active pocket of the enzyme via the formation of various interactions with the key amino acid residues.

Development of Novel (+)-Nootkatone Thioethers Containing 1,3,4-Oxadiazole/Thiadiazole Moieties as Insecticide Candidates against Three Species of Insect Pests

To improve the insecticidal activity of (+)-nootkatone, a series of 42 (+)-nootkatone thioethers containing 1,3,4-oxadiazole/thiadiazole moieties were prepared to evaluate their insecticidal activities against Mythimna separata Walker, Myzus persicae Sulzer, and Plutella xylostella Linnaeus. Insecticidal evaluation revealed that most of the title derivatives exhibited more potent insecticidal activities than the precursor (+)-nootkatone after the introduction of 1,3,4-oxadiazole/thiadiazole on (+)-nootkatone. Among all of the (+)-nootkatone derivatives, compound 8c (1 mg/mL) exhibited the best growth inhibitory (GI) activity against M. separata with a final corrected mortality rate (CMR) of 71.4%, which was 1.54- and 1.43-fold that of (+)-nootkatone and toosendanin, respectively; 8c also displayed the most potent aphicidal activity against M. persicae with an LD50 value of 0.030 μg/larvae, which was closer to that of the commercial insecticidal etoxazole (0.026 μg/larvae); and 8s showed the best larvicidal activity against P. xylostella with an LC50 value of 0.27 mg/mL, which was 3.37-fold that of toosendanin and slightly higher than that of etoxazole (0.28 mg/mL). Furthermore, the control efficacy of 8s against P. xylostella in the pot experiments under greenhouse conditions was better than that of etoxazole. Structure-activity relationships (SARs) revealed that in most cases, the introduction of 1,3,4-oxadiazole/thiadiazole containing halophenyl groups at the C-13 position of (+)-nootkatone could obtain more active derivatives against M. separata, M. persicae, and P. xylostella than those containing other groups. In addition, toxicity assays indicated that these (+)-nootkatone derivatives had good selectivity to insects over nontarget organisms (normal mammalian NRK-52E cells and C. idella and N. denticulata fries) with relatively low toxicity. Therefore, the above results indicate that these (+)-nootkatone derivatives could be further explored as new lead compounds for the development of potential eco-friendly pesticides.

4-Alkyl-1,2,4-triazole-3-thione analogues as metallo-β-lactamase inhibitors

In Gram-negative bacteria, the major mechanism of resistance to β-lactam antibiotics is the production of one or several β-lactamases (BLs), including the highly worrying carbapenemases. Whereas inhibitors of these enzymes were recently marketed, they only target serine-carbapenemases (e.g. KPC-type), and no clinically useful inhibitor is available yet to neutralize the class of metallo-β-lactamases (MBLs). We are developing compounds based on the 1,2,4-triazole-3-thione scaffold, which binds to the di-zinc catalytic site of MBLs in an original fashion, and we previously reported its promising potential to yield broad-spectrum inhibitors. However, up to now only moderate antibiotic potentiation could be observed in microbiological assays and further exploration was needed to improve outer membrane penetration. Here, we synthesized and characterized a series of compounds possessing a diversely functionalized alkyl chain at the 4-position of the heterocycle. We found that the presence of a carboxylic group at the extremity of an alkyl chain yielded potent inhibitors of VIM-type enzymes with Ki values in the μM to sub-μM range, and that this alkyl chain had to be longer or equal to a propyl chain. This result confirmed the importance of a carboxylic function on the 4-substituent of 1,2,4-triazole-3-thione heterocycle. As observed in previous series, active compounds also preferentially contained phenyl, 2-hydroxy-5-methoxyphenyl, naphth-2-yl or m-biphenyl at position 5. However, none efficiently inhibited NDM-1 or IMP-1. Microbiological study on VIM-2-producing E. coli strains and on VIM-1/VIM-4-producing multidrug-resistant K. pneumoniae clinical isolates gave promising results, suggesting that the 1,2,4-triazole-3-thione scaffold worth continuing exploration to further improve penetration. Finally, docking experiments were performed to study the binding mode of alkanoic analogues in the active site of VIM-2.
