Check Digit Verification of cas no

The CAS Registry Mumber 175205-58-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,5,2,0 and 5 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 175205-58:
(8*1)+(7*7)+(6*5)+(5*2)+(4*0)+(3*5)+(2*5)+(1*8)=130
130 % 10 = 0
So 175205-58-0 is a valid CAS Registry Number.

A facile synthesis of ethyl-2-methyl-5H-chromeno[3,4-c]pyridine-1- carboxylates

Ramadas,Krupadanam, G.L. David

, p. 1103 - 1114 (2000)

4-Chloro-2H-3-chromene carbaldehydes (2a-i) on reaction with ethyl-3- aminocrotonate 3 gives ethyl-2-methyl-5H-chromeno[3,4-c]pyridine-1- carboxylates 4a-i in good yields.

Synthesis and antimicrobial activity of 2-(4-phenyl-2h-chromen-3-yl)-1h-benzo[d]imidazole

, p. 1723 - 1728 (2021/07/31)

A new series of 4-phenyl-2H-chromene-3-benzimidazoles (8a-o) were synthesized by the condensation of 4-phenyl-2H-chromene-3- carbaldehyde with o-phenylene diamines. The products were purified through column chromatography and structures of these compounds were characterized by IR, 1H & 13C NMR and mass spectral data. All the final compounds were screened for their antimicrobial activity and their efficacy were matched with ciprofloxacin. Five compounds (8b, 8d, 8i, 8l and 8o) were found to be most effective compounds of this series and with activities improved than ciprofloxacin under the tested conditions.

Design, Synthesis, and Antimicrobial Activity of (E)-4-Phenyl-2H-chromene-3-carbaldehyde O-[(1-Phenyl-1H-1,2,3-triazol-4-yl)methyl]oxime Derivatives

Chittneni, P. Rao,Dasari, R.,Thalari, G.,Yerrabelly, J. Rao

, p. 1519 - 1532 (2021/10/26)

Abstract: A new series of 1,4-disubstituted 1,2,3-triazole derivatives tethered to a2H-chromene scaffold have beensynthesized via a click reaction. The synthesized chromene–triazole conjugateswere screened for their antibacterial activity against E. coli, S. aureus, P. aeruginosa and B.subtilis, as well as for antifungal activity against A. niger and C. albicans. Among the 17 synthesized compounds, 6 derivativesshowed the best antimicrobial activity. Molecular docking studies of the titlecompounds with carotenoid dehydrosqualene synthase (PDB: 2ZCS) revealed dockingscores within the range 98.241–91.488 against 106.573 for the reference ligandCiprofloxacin and with lanosterol 14α-demethylase (CYP51; PDB ID: 5V5Z),103.672–96.917 against 110.839 for the reference ligand Voriconazole.

, (2020/06/22)

Cycloaddition reaction of 4-chloro-2-oxo-2H-chromene-3-carbaldehydes (3a-g) and 4-chloro-2H-chromene-3-carbaldehydes (7a-h) with activated alkynes (4a-b) provided the 2-oxo-2H-chromenyl-5-oxo-2,5-dihydrofuran-3-carboxylates (5a-n) and 2H-chromenyl-5-oxo-2,5-dihydrofuran-3-carboxylates (8a-p). All the prepared compounds were screened for anti-inflammatory activity. In vitro anti-inflammatory activity data demonstrated that the compounds 5g, 5i, 5k-l and 8f are effective among the tested compounds against TNF-α (1.108 ± 0.002, 0.423 ± 0.022, 0.047 ± 0.001, 0.070 ± 0.002 and 0.142 ± 0.001 μM) in comparison with standard compound Prednisolone (0.033 ± 0.002 μM). Based on in vitro results, three compounds (5i, 5k and 8f) have been selected for in vivo experiments and these compounds are identified as better compounds with respect to anti-inflammatory activity in LPS induced mice model. Compound 5i was identified as potent and showed significant reduction in TNF-α and IL-6.
