Check Digit Verification of cas no

The CAS Registry Mumber 83169-98-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,1,6 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 83169-98:
(7*8)+(6*3)+(5*1)+(4*6)+(3*9)+(2*9)+(1*8)=156
156 % 10 = 6
So 83169-98-6 is a valid CAS Registry Number.

A Macrocyclic 1,4-Diketone Enables the Synthesis of a p-Phenylene Ring That Is More Strained than a Monomer Unit of [4]Cycloparaphenylene

Mitra, Nirmal K.,Corzo, Hector H.,Merner, Bradley L.

, p. 3278 - 3281 (2016)

The synthesis of a p-terphenyl-based macrocycle, containing a p-phenylene unit with 42.6 kcal/mol of strain energy (SE), is reported. The conversion of a macrocyclic 1,4-diketone to a highly strained arene system takes place over five synthetic steps, fea

Structural chemistry and anti-inflammatory activity of flexible/restricted phenyl dimers

Singh, Ved Prakash,Dowarah, Jayanta,Tewari, Ashish Kumar,Geiger, David K.

, p. 1289 - 1303 (2020/01/22)

Three phenyl dimer compounds, namely 3,3′-Diformyldiphenoxyethane (C16H14O4) (1), 1-(4-[2-(4-Acetyl-phenoxy)-ethoxy]-phenyl)-ethanone (C17H16N2O3) (2), 1-{4-[2-(4-Acetyl-phenoxymethyl)-benzyloxy]-phenyl}-ethanone (C24H22O4) (3), were obtained and fully characterized, including their crystal structure determinations. The structural properties of two compounds 4, 4′-(ethylenedioxy)dibenzaldehyde) (C16H14O4) (Tewari et al. Acta Cryst. E63:o1930, 2007) [1] (4) and 4-(2-Phenoxy-ethoxy)-benzaldehyde (C15H14O3) (Valgera et al. CCDC 710835, 2016) [2] (5) are discussed with the role of the substituent in crystal packing. In vivo, anti-inflammatory activities of all compounds were studied on Wistar strain albino rats. All the compounds exhibited anti-inflammatory activity except 5. Compounds 1, 2, 4 have shown moderate-to-intermediate effects on inhibitory properties. Compound (3) with restricted rotation in the compound-like SC-558 drug was shown to possess good inhibitory properties at 180?min. In silico analysis was performed and compared with experimental in vivo results.

Synthesis, Antimicrobial Evaluations, and DNA Photo Cleavage Studies of New Bispyranopyrazoles

Yusuf, Mohamad,Kaur, Manvinder,Sohal, Harvinder Singh

, p. 706 - 713 (2017/02/05)

The bispyranopyrazoles (4a, 4b, 4c, 4d, 4e, 4f, 4g) were synthesized from the reactions of dibenzaldehydes (2a, 2b, 2c, 2d, 2e, 2f, 2g) with 3-methylpyrazole-5-one 3 and malononitrile by refluxing under alcoholic medium. The dibenzaldehydes were obtained from the O-alkylation of 3-hydroxybenzaldehyde with suitable 1,ω-dibromoalkanes under the alkaline conditions in the presence of dry EtOH/DMF. The structures of bisheterocyclics were determined from rigorous analysis of their spectral parameters (IR,1H-NMR,13C-NMR, and ESI-MS). The newly prepared compounds were screened for their antimicrobial activity against seven bacterial and five fungal strains. The DNA photo cleavage potential of these compounds was also evaluated by using agarose gel electrophoresis, and bispyranopyrazoles 4b, 4d and 4e exhibited significant level of DNA photocleavage activity.

Ring-closing metathesis reaction-based synthesis of new classes of polyether macrocyclic systems

Naveen,Babu, Srinivasarao Arulananda

supporting information, p. 7758 - 7781 (2015/09/08)

Ring closing metathesis (RCM) reactions of suitable substrates having terminal olefins, which are assembled from various linkers and hydroxy benzaldehydes and syntheses of a wide range of 16-30 membered, new crown ether-type polyether, aza-polyether, bis aza-polyether macrocycles and dilactone moiety embedded polyether macrocycles (macrolides) are reported. After the ring-closure reaction, installation of different functional groups and functional group modification on the periphery of the synthesized polyether/crown ether macrocycles obtained in the RCM reactions are accomplished using the epoxidation, oxidation and catalytic hydrogenation-based synthetic transformations. Along this line, the syntheses of a variety of polyether macrocycles possessing epoxide or α-hydroxy ketone or 1,2-diol functionalities at the periphery have been shown. Furthermore, the synthesized α-hydroxy ketone functionality installed polyether macrocycles were subjected to the allylation and Reformatsky type reactions to obtain homoallyl alcohol moiety-based and lactone ring-appended polyether macrocycles.
