24805-50-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24805-50-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,8,0 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 24805-50:
(7*2)+(6*4)+(5*8)+(4*0)+(3*5)+(2*5)+(1*0)=103
103 % 10 = 3
So 24805-50-3 is a valid CAS Registry Number.

Paragraph 0076; 0084-0085, (2021/06/09)

The invention provides a phthalimide compound or a pharmaceutically acceptable salt thereof, wherein the structure of the phthalimide compound is shown as a formula I; in the formula I, R1 is selected from hydrogen, aliphatic hydrocarbon, alkoxy and halogen; R2 and R3 are the same or different and are selected from hydrogen, aliphatic hydrocarbon, alkoxy and halogen; or R2, R3 and connected N atoms are cyclized to form a closed substituted or unsubstituted five-membered or six-membered ring; R1, R2 and R3 can be unsubstituted or substituted by straight chain or branched chain alkyl or alkoxy selected from C1 - C10 and halogen; and R1, R2 and R3 are not hydrogen at the same time. The compound disclosed by the invention has the effect of a ROCK inhibitor and an anti-tumor effect, and is expected to be used as a clinical medicine with a relatively high therapeutic index.

Catalytic Asymmetric Conjugate Addition and Sulfenylation of Diarylthiazolidin-2,4-diones

Jiao, Lihui,Bu, Liwei,Ye, Xinyi,Zhao, Xiaowei,Jiang, Zhiyong

, p. 9620 - 9629 (2016/11/02)

This work reports the first application of diarylthiazolidin-2,4-diones as nucleophiles in asymmetric catalysis. By utilizing chiral amino acid-based (thio)urea-tertiary amines as the catalysts, we successively established asymmetric conjugate addition to nitroolefins and sulfenylation to N-(sulfanyl)-succinimides of diarylthiazolidin-2,4-diones. Two series of biologically important 5-aryl-5-substituted thiazolidin-2,4-diones were obtained with high enantio- and diastereoselectivities (up to >99% ee and >19:1 dr). The enantioenriched adducts were found to show satisfactory anticancer activities against three different cancer cell lines using the MTT assay. All of these successes depended on the development of a general and expedient synthetic strategy to provide diverse 5H-thiazolidin-2,4-diones.

Quinolinecarboxylic Acids. 3. Synthesis and Antibacterial Evaluation of 2-Substituted-7-oxo-2,3-dihydro-7H-pyridobenzothiazine-6-carboxylic Acids Related to Rufloxacin

, p. 3449 - 3454 (2007/10/02)

A series of 2-substituted-7-oxo-2,3-dihydro-7H-pyridobenzothiazine-6-carboxylic acids has been prepared and evaluated for in vitro antibacterial activity.These derivatives were less active than corresponding desmethylated analogues.Among th
