81445-91-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81445-91-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,4,4 and 5 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 81445-91:
(7*8)+(6*1)+(5*4)+(4*4)+(3*5)+(2*9)+(1*1)=132
132 % 10 = 2
So 81445-91-2 is a valid CAS Registry Number.

Structure-Activity Relationships of Nogalamycin Analogues
Wiley, Paul F.,Elrod, David W.,Houser, David J.,Richard, Floyd A.
, p. 560 - 567 (2007/10/02)
Nogalamycin (1) has been modified by changes at C-10 and C-7 and in the dimethylamino group to prepare an extensive series of analogues.The chemistry involved in the modifications and structure-activity relationships among these nogalamycin analogues are discussed, as well as comparisons with previously reported compounds 1, 7-con-O-methylnogarol (2), and disnogamycin (11).
