Check Digit Verification of cas no

The CAS Registry Mumber 19462-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,4,6 and 2 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 19462-98:
(7*1)+(6*9)+(5*4)+(4*6)+(3*2)+(2*9)+(1*8)=137
137 % 10 = 7
So 19462-98-7 is a valid CAS Registry Number.

Benzimidazole Ribonucleosides: Design, Synthesis, and Antiviral Activity of Certain 2-(Alkylthio)- and 2-(Benzylthio)-5,6-dichloro-1-(β-D-ribofuranosyl)benzimidazoles

Devivar, Rodrigo V.,Kawashima, Etsuko,Revankar, Ganapathi R.,Breitenbach, Julie M.,Kreske, Edward D.,et al.

, p. 2942 - 2949 (1994)

Several 2-alkylthio and 2-benzylthio derivatives of 5,6-dichloro-1-(β-D-ribofuranosyl)benzimidazole (DRB) have been designed and synthesized from 5,6-dichloro-1-(β-D-ribofuranosyl)benzimidazole-2-thione.All compounds were evaluated for activity against hu

Design, synthesis, and antitumor activity of PLGA nanoparticles incorporating a discovered benzimidazole derivative as EZH2 inhibitor

Elkot, Hoda A.,Ragab, Ibrahim,Saleh, Noha M.,Amin, Mohamed N.,Al-Rashood, Sara T.,El-Messery, Shahenda M.,Hassan, Ghada S.

, (2021/05/31)

Purpose: Targeting enhancer of zeste homolog 2 (EZH2) can represent a hopeful strategy for oncotherapy. Also, the use of PLGA-based nanoparticles as a novel and rate-controlling carrier system was of our concern. Methods: Benzimidazole derivatives were synthesized, and their structures were clarified. In vitro antitumor activity was evaluated. Then, a modeling study was performed to investigate the ability of the most active compounds to recognize EZH2 active sites. Compound 30 (Drug) was selected to conduct pre-formulation studies and then it was incorporated into polymeric PLGA nanoparticles (NPs). NPs were then fully characterized to select an optimized formula (NP4) that subjected to further evaluation regarding antitumor activity and protein expression levels of EZH2 and EpCAM. Results: The results showed the antitumor activity of some synthesized derivatives. Docking outcomes demonstrated that Compound 30 was able to identify EZH2 active sites. NP4 exhibited promising findings and proved to keep the antitumor activity of Compound 30. HEPG-2 was the most sensitive for both Drug and NP4. Protein analysis indicated that Drug and NP4 had targeted EZH2 and the downstream signaling pathway leading to the decline of EpCAM expression. Conclusions: Targeting EZH2 by Compound 30 has potential use in the treatment of cancer especially hepatocellular carcinoma.

Highly Diastereoselective Synthesis of Dihydro-benzoimidazo-[1,3]-thiazines via Electro-oxidative Selenocyclization of Thioallyl Benzoimidazoles

Halder, Atreyee,Mahanty, Kingshuk,Maiti, Debabrata,De Sarkar, Suman

supporting information, p. 3895 - 3899 (2021/10/23)

The current methodology reveals a green and proficient electro-oxidative tandem selenocyclization of thioallyl benzoimidazoles manufacturing selenylated dihydro-benzoimidazo-thiazine derivatives. Both C?Se and C?N bond formation were achieved via this mild protocol which exhibits good functional group tolerability affording an extensive range of substrate scope up to 96% isolated yields. Complete control over the regioselective formation of the six-membered heterocycle and stereoselective construction of the contiguous stereocenters was established. The practical electrochemical method operates in an undivided cell at ambient temperature without using any metal and external chemical oxidant.

, p. 4221 - 4224 (2013/07/25)

A series of 19 new 2-{[2-(1H-imidazol-1-yl)ethyl]sulfanyl}-1H-benzimidazole derivatives was synthesized starting from the properly substituted 1,2-phenylendiamine. These compounds have hydrogen or methyl at position 1; while hydrogen, chlorine, ethoxy or methoxycarbonyl group is at position 5 and/or 6. The novel compounds were tested against protozoa Trichomonas vaginalis, Giardia intestinalis and Entamoeba histolytica. Experimental evaluations revealed strong activity for all tested compounds, having IC 50 values in the nanomolar range, which were even better than metronidazole, the drug of choice for these parasites.

Valdez, Juan,Cedillo, Roberto,Hernandez-Campos, Alicia,Yepez, Lilian,Hernandez-Luis, Francisco,Navarrete-Vazquez, Gabriel,Tapia, Amparo,Cortes, Rafael,Hernandez, Manuel,Castillo, Rafael

, p. 2221 - 2224 (2007/10/03)

Compounds 1-18 have been synthesized and tested in vitro against the protozoa Giardia lamblia, Entamoeba histolytica and the helminth Trichinella spiralis. Inhibition of rat brain tubulin polymerization was also measured and compared for each compound. Results indicate that most of the compounds tested were more active as antiprotozoal agents than Metronidazole and Albendazole. None of the compounds was as active as Albendazole against T. spiralis. Although only compounds 3, 9 and 15 (2-methoxycarbonylamino derivatives) inhibited tubulin polymerization, these were not the most potent antiparasitic compounds.
