55851-38-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55851-38-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,8,5 and 1 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55851-38:
(7*5)+(6*5)+(5*8)+(4*5)+(3*1)+(2*3)+(1*8)=142
142 % 10 = 2
So 55851-38-2 is a valid CAS Registry Number.

Potential Antitumor Agents. 48. 3'-Dimethylamino Derivatives of Amsacrine: Redox Chemistry and in Vivo Tumor Activity

Atwell, Graham J.,Rewcastle, Gordon W.,Baguley, Bruce C.,Denny, William A.

, p. 652 - 658 (1987)

Structure-activity relationships for a series of acridine-substituted 3'-N(CH3)2 derivatives of the clinical antileukemic drug amsacrine (1) are reported.The parent (unsubstituted) compound 3 has activity against the Lewis lung solid tumor that is superior to amsacrine(1), the new clinical amsacrine analogue 4, and the recently developed 3'-NHCH3 derivative 2.Although the compounds generally bind less well to DNA and are less dose potent in vivo than either their amsacrine (3'-OCH3) or 3'-NHCH3 analogues, they show very high levels of antitumor activity, with the 4-OCH3 derivative capable of effecting 100percent cures of the Lewis lung solid tumor.The broad structure-activity relationships for acridine substitution more closely resemble those of the amsacrine than the 3'-NHCH3 series, with 4-substituted and 4,5-disubstituted compounds showing the highest activity.
