Check Digit Verification of cas no

The CAS Registry Mumber 172992-24-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,9,9 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 172992-24:
(8*1)+(7*7)+(6*2)+(5*9)+(4*9)+(3*2)+(2*2)+(1*4)=164
164 % 10 = 4
So 172992-24-4 is a valid CAS Registry Number.

Inhibition of growth of B16 murine melanoma cells by novel spermine analogues

Carrington,Qarawi,Blagbrough,Moss,Pouton

, p. 25 - 27 (2007/10/03)

To develop new cytotoxins, which could find use as anti-cancer agents, polyamine conjugates were synthesized containing spermine and an anthracene or acridine unit. Spermine is known to groove-bind to DNA; anthracene and acridine are known to intercalate. It was hoped that these polyamine-polyaromatic conjugates would use both modes of binding. Studies of growth inhibition of B16 murine melanoma cells showed the conjuates to be more effective than either spermine, anthracene-9-carboxylic acid or acridine-9-carboxylic acid, and of the conjugates, the acridine derivative showed greatest activity.
