Check Digit Verification of cas no

The CAS Registry Mumber 1280582-84-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,5,8 and 2 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1280582-84:
(9*1)+(8*2)+(7*8)+(6*0)+(5*5)+(4*8)+(3*2)+(2*8)+(1*4)=164
164 % 10 = 4
So 1280582-84-4 is a valid CAS Registry Number.

Synthesis and preliminary in-vitro cytotoxic activity of novel substituted diaryl-imidazo [2, 1, b]-benzothiazole derivatives

Malik, Jitender K.,Noolvi, Malleshappa N.,Manvi, Fakkirappa V.,Nanjwade,Patel, Harun M.,Manjula,Rao, Mallikarjuna C.,Barve, Ashutosh

, p. 717 - 724 (2012/04/05)

A novel series of substituted diaryl imidazo[2, 1-b]benzothiazole derivatives (8a-y) were synthesized by condensation reaction between 2-amino benzothiazole derivatives (3a-g) and substituted a-bromo-1, 2-(substituted) diaryl-1-ethanones (7a-i). The structures of the synthesized compounds were established by IR, 1H NMR, 13C NMR and mass spectroscopical data. The compounds (8a-y) were evaluated for their in-vitro cytotoxic activity on murine (B16F10) and human (MCF-7) cancer cells by using MTT assay. From the in vitro studies compounds 8p, 8u and 8y were found most effective with an IC50 range of 0.56-27.50 μM in MCF-7 and 2.57-36.54 μM in B16F10 cells.
