153333-52-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 153333-52-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,3,3 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 153333-52:
(8*1)+(7*5)+(6*3)+(5*3)+(4*3)+(3*3)+(2*5)+(1*2)=109
109 % 10 = 9
So 153333-52-9 is a valid CAS Registry Number.

Phase-Transfer-Catalyzed Asymmetric Annulations of Alkyl Dihalides with Oxindoles: Unified Access to Chiral Spirocarbocyclic Oxindoles

Gao, Min,Hu, Lin,Li, Xuemin,Li, Yongyi

, p. 875 - 880 (2022/02/05)

A general phase-transfer-catalyzed asymmetric (n+1) (n = 4 or 5) annulation reaction, featuring the direct coupling of simple oxindoles with alkyl dihalides that are allylic/benzylic and non-allylic/benzylic, has been developed to provide previously inacc

2-(substituted phenyl)-3,4-dihydroisoquinolin-2-iums as novel antifungal lead compounds: Biological evaluation and structure-activity relationships

Hou, Zhe,Yang, Rui,Zhang, Cen,Zhu, Li-Fei,Miao, Fang,Yang, Xin-Juan,Zhou, Le

, p. 10413 - 10424 (2013/10/22)

The title compounds are a class of structurally simple analogues of quaternary benzo[c]phenanthridine alkaloids (QBAs). In order to develop novel QBA-like antifungal drugs, in this study, 24 of the title compounds with various substituents on the N-phenylring were evaluated for bioactivity against seven phytopathogenic fungi using the mycelial growth rate method and their SAR discussed. Almost all the compounds showed definite activities in vitro against each of the test fungi at 50 μg/mL and a broad antifungal spectrum. In most cases, the mono-halogenated compounds 2-12 exhibited excellentactivities superior to the QBAs sanguinarine and chelerythrine. Compound 8 possessed the strongest activities on each of the fungi with EC50 values of 8.88-19.88 μg/mL and a significant concentration-dependent relationship. The SAR is as follows: the N-phenyl group is a high sensitive structural moiety for the activity and the characteristics and position of substituents intensively influence the activity. Generally, electron-withdrawing substituents remarkably enhance the activity while electron-donating substituents cause a decrease of the activity. In most cases, ortha- and para-halogenated isomers were more active than the corresponding m-halogenated isomers. Thus, the title compounds emerged as promising lead compounds for the development of novel biomimetic antifungal agrochemicals. Compounds 8 and 2 should have great potential as new broad spectrum antifungal agents for plant protection.
