255376-41-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 255376-41-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,5,3,7 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 255376-41:
(8*2)+(7*5)+(6*5)+(5*3)+(4*7)+(3*6)+(2*4)+(1*1)=151
151 % 10 = 1
So 255376-41-1 is a valid CAS Registry Number.

Design, synthesis and biological evaluation of 3-substituted indenoisoquinoline derivatives as topoisomerase I inhibitors

Zhao, Qian,Xu, Xi,Xie, Zhouling,Liu, Xiao,You, Qidong,Guo, Qinglong,Zhong, Yi,Li, Zhiyu

, p. 1068 - 1072 (2016/05/24)

A new series of indenoisoquinoline derivatives was designed and synthesized. The in vitro anti-proliferative activity of these novel compounds was evaluated in HepG2, A549 and HCT-116 cell lines. Compounds 9a, 9b, 10a, 10c, 10e, 18a and 18b manifested potent inhibitory activity against the three tested cancer cell lines. Nineteen compounds were also tested for Top I inhibition at 50 μM. Almost all the tested compounds showed potent Top I inhibition activity at this concentration. The most potent compounds 9a and 10a demonstrated more cytotoxicity than HCPT and TPT and was comparable to CPT in inhibitory activities on Top I in our biological assay.

NOVEL INHIBITOR COMPOUNDS OF PHOSPHODIESTERASE TYPE 10A

Paragraph 0991; 0992, (2013/05/21)

The present invention relates to compounds which are inhibitors of phosphodiesterase type 10A and to their use for the manufacture of a medicament and which thus are suitable for treating or controlling of medical disorders selected from neurological diso

Synthesis of indolin-2-one, isoindolin-1-one, and indole derivatives from homophthalic acid

Kilikli, Alper A.,Dengiz, Cagatay,Oezcan, Sevil,Balci, Metin

experimental part, p. 3697 - 3705 (2011/12/21)

We hereby report the preparation of indolin-2-one and isoindolin-1-one and their derivatives starting from 2-(carboxymethyl)benzoic acid, which was first regiospecifically converted into the isomeric half esters. Transformation of the acid functionalities to the acyl azides followed by Curtius rearrangement gave the regioisomeric isocyanates. Reaction of the isocyanates with aniline produced urethane derivatives. Intramolecular cyclization provided the target compounds. Georg Thieme Verlag Stuttgart. New York.
