Check Digit Verification of cas no

The CAS Registry Mumber 90176-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,1,7 and 6 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90176-39:
(7*9)+(6*0)+(5*1)+(4*7)+(3*6)+(2*3)+(1*9)=129
129 % 10 = 9
So 90176-39-9 is a valid CAS Registry Number.

Design, synthesis and biological evaluation of novel flavone Mannich base derivatives as potential antibacterial agents

Lv, Xian-Hai,Liu, Hao,Ren, Zi-Li,Wang, Wei,Tang, Feng,Cao, Hai-Qun

, p. 299 - 306 (2019)

Abstract: A series of novel Mannich base derivatives of flavone containing benzylamine moiety was synthesized using the Mannich reaction. The results of antifungal activity are not ideal, but its antifungal effect has a certain increase compared to flavonoids. After that, four bacteria were used to test antibacterial experiments of these compounds; compound 5g (MIC = 0.5, 0.125?mg/L) showed significant inhibitory activity against Staphylococcus aureus and Salmonella gallinarum compared with novobiocin (MIC = 2, 0.25?mg/L). Compound 5s exhibited broad spectrum antibacterial activity (MIC = 1, 0.5, 2, 0.05?mg/L) against four bacteria. The selected compounds 5g and 5s exhibit potent inhibition against Topo II and Topo IV with IC50 values (0.25–16?mg/L). Molecular docking model showed that the compounds 5g and 5s can bind well to the target by interacting with amino acid residues. It will provide some valuable information for the commercial antibacterial agents. Graphical Abstract: [Figure not available: see fulltext.].

Prednisolone succinate-glucosamine conjugate: Synthesis, characterization and in vitro cellular uptake by kidney cell lines

Lin, Yan,Sun, Xun,Gong, Tao,Zhang, Zhi Rong

scheme or table, p. 25 - 28 (2012/04/04)

Prednisolone succinate-glucosamine (PSG) conjugate, a prodrug for prednisolone, was synthesized and confirmed by NMR and MS spectrum. The stabilities of the prodrug in PBS (pH 2.50, 5.00, 7.20, and 7.89) were studied. Cytotoxicity and uptake assay of the prodrug were perfomed on HK-2 and MDCK cell lines. The results showed that compared with prednisolone, the PSG not only did not increase the cytotoxicity but also improved the uptake to 2.2 times of prednisolone by the cells. Thus, it indicated that glucosamine might be a potential carrier for kidney-targeting delivery of prednisolone.
