Check Digit Verification of cas no

The CAS Registry Mumber 3156-51-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,5 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3156-51:
(6*3)+(5*1)+(4*5)+(3*6)+(2*5)+(1*1)=72
72 % 10 = 2
So 3156-51-2 is a valid CAS Registry Number.

Canthine analogs via intramolecular Diels-Alder reactions

Markgraf, J. Hodge,Finkelstein, Manuel,Cort, John R.

, p. 461 - 470 (1996)

Carbocyclic analogs (10 and 12) of canthine (1) and canthin-6-one (2) were prepared in three and four steps, respectively, from indole-3-carboxyaldehyde. The key step was an intramolecular Diels-Alder reaction carried out in refluxing sulfolane.

Dipolar HCP materials as alternatives to DMF solvent for azide-based synthesis

Bai, Rongxian,Gao, Feng,Gu, Yanlong,Li, Minghao

supporting information, p. 7499 - 7505 (2021/10/12)

Hypercrosslinked polymers HCP-DMF and HCP-DMF-SO3H containing abundant and flexible DMF moieties were designed and synthesized. Benefitting from the solvation microenvironment provided by the pseudo-DMF moities, the polar HCPs manifested outstanding performances in the conversions of NaN3 to benzylic azides and 1,2,3-triazoles in EtOH (95%), respectively, avoiding the use of risky DMF and improving the separation processes of the products.

Exploiting the chiral ligands of bis(Imidazolinyl)-and bis(oxazolinyl)thiophenes—Synthesis and application in Cu-catalyzed friedel–crafts asymmetric alkylation

Al-Majid, Abdullah Mohammed,Alammari, Abdullah Saleh,Alshahrani, Saeed,Barakat, Assem,Haukka, Matti,Islam, Mohammad Shahidul

, (2021/12/17)

Five new C2-symmetric chiral ligands of 2,5-bis(imidazolinyl)thiophene (L1–L3) and 2,5-bis(oxazolinyl)thiophene (L4 and L5) were synthesized from thiophene-2,5-dicarboxylic acid (1) with enantiopure amino alcohols (4a–c) in excellent optical purity and chemical yield. The util-ity of these new chiral ligands for Friedel–Crafts asymmetric alkylation was explored. Subse-quently, the optimized tridentate ligand L5 and Cu(OTf)2 catalyst (15 mol%) in toluene for 48 h promoted Friedel–Crafts asymmetric alkylation in moderate to good yields (up to 76%) and with good enantioselectivity (up to 81% ee). The bis(oxazolinyl)thiophene ligands were more potent than bis(imidazolinyl)thiophene analogues for the asymmetric induction of the Friedel–Crafts asymmetric alkylation.

Streptindole and Its Derivatives as Novel Antiviral and Anti-Phytopathogenic Fungus Agents

Ding, Xin,Gao, Yongyue,Kang, Jin,Ma, Dejun,Wang, Qingmin,Wang, Ziwen,Zhang, Mingjun

, p. 7839 - 7849 (2020/09/01)

Plant diseases caused by plant viruses and pathogens seriously affect the production and storage of food crops. With the emergence of drug resistance, it is very difficult to control. Natural products are the source of new drug discovery. Here, the natural product streptindole was found to have good antiviral activity against tobacco mosaic virus (TMV) and fungicidal activities against 14 kinds of phytopathogenic fungi. A series of derivatives of streptindole were designed, synthesized, and evaluated for their antiviral and fungicidal activities. Compounds 4, 5, 11, 12c, 12d, 13d, and 13i-13l showed higher anti-TMV activities than ribavirin (inhibitory rate: 38, 37, and 40% at 500 μg/mL for inactivation, curative, and protection activity in vivo, respectively), among which compound 12d (inhibitory rate: 57, 55, and 53% at 500 μg/mL for inactivation, curative, and protection activity in vivo, respectively) with excellent antiviral activity was further evaluated for the mode of action. The mechanism research revealed that 12d can break the three-dimensional structure of TMV coat protein (CP) through hydrogen bonds, thus inhibiting the assembly of virus particles. The molecular docking result showed that compound 12d did exhibit strong interaction with TMV CP. The derivatives of streptindole also displayed broad-spectrum fungicidal activities. The current study provided valuable insights into the antiviral and fungicidal activities of streptindole derivatives.
