21900-25-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 21900-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,0 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 21900-25:
(7*2)+(6*1)+(5*9)+(4*0)+(3*0)+(2*2)+(1*5)=74
74 % 10 = 4
So 21900-25-4 is a valid CAS Registry Number.

, p. 2307 - 2317 (2016/04/26)

New phenothiazine derivatives 6-20 have been designed, synthesized and evaluated in vitro for their ability to inhibit tubulin polymerization and antiproliferative activity against 60 cancer cell lines, including several multi-drug resistant (MDR) tumor cell lines. The phenothiazine unit may successfully replace the classical 3,4,5-trimethoxyphenyle A ring of parent combretastatin A-4 or phenstatin, confirming previous studies. The most promising structural modulations have been realized on the B ring, the 2′-fluoro-4′-methoxy substitution in compound 6 and the 2′-trifluoromethyl-4′-methoxy substitution in compound 7 providing the best antitubulin and antitumor activity in the current study. Compounds 6-8 and 16 exhibited more important cell growth inhibition than parent phenstatin 2 on human colon Duke's type D, colorectal adenocarcinoma COLO 205 and on human kidney adenocarcinoma A498 cell lines. 10-Methylphenothiazine derivatives 19 and 20 did not show biological activity but exerted bright fluorescence and solvatochromism effects. These molecules deserve further chemical efforts in order to provide valuable tools for biophysical studies.

scheme or table, p. 6017 - 6025 (2012/03/08)

Polythiophenes with alcohol, tosylate, azide, ethynylene, carboxylic acid, and amine end groups were prepared by a combination of functionalized nickel initiators and postpolymerization reactions. The azide and ethynylene polymers were subsequently used in a click reaction to produce a conjugated block copolymer. Finally, a conjugated triblock-copolymer was synthesized by means of a chain growth polymerization initiated by a binuclear nickel initiator.
