Check Digit Verification of cas no

The CAS Registry Mumber 79867-80-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,8,6 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 79867-80:
(7*7)+(6*9)+(5*8)+(4*6)+(3*7)+(2*8)+(1*0)=204
204 % 10 = 4
So 79867-80-4 is a valid CAS Registry Number.

Enhanced Antitumor Properties of 3'-(4-Morpholinyl) and 3'-(4-Methoxy-1-piperidinyl) Dervatives of 3'-Deaminodaunorubicin

Mosher, Carol W.,Wu, Helen Y.,Fujiwara, Allan N.,Acton, Edward M.

, p. 18 - 24 (2007/10/02)

Reductive N,N-dialkylation of daunorubicin with 2,2'-oxydiacetaldehyde and NaBH3CN occurred in two steps without interruption and with cyclization to form 3'-(4-morpholinyl)-3'-deaminodaunorubicin.This derivative retained the antitumor efficacy of doxorubicin against mouse leukemia P388 but at one-fortieth the dose; hence, it is the most potent anthracycline analogue synthesized so far.The 4-methoxy-1-piperidinyl derivative, similarly prepared with 3-methoxyglutaraldehyde, showed improved efficacy against P388, though at normal doses.Results with a series of analogues indicate that incorporation of the N in the new ring and the presence of an ether O at the 4-position are critical for enhanced activity.
