Check Digit Verification of cas no

The CAS Registry Mumber 452071-65-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,2,0,7 and 1 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 452071-65:
(8*4)+(7*5)+(6*2)+(5*0)+(4*7)+(3*1)+(2*6)+(1*5)=127
127 % 10 = 7
So 452071-65-7 is a valid CAS Registry Number.

Novel anthracycline oligosaccharides: Influence of chemical modifications of the carbohydrate moiety on biological activity

Cipollone, A,Berettoni, M,Bigioni, M,Binaschi, M,Cermele, C,Monteagudo, E,Olivieri, L,Palomba, D,Animati, F,Goso, C,Maggi

, p. 1459 - 1470 (2007/10/03)

Several observations highlight the importance of the carbohydrate moiety for the biological activity of antitumoural anthracyclines. Here is reported the synthesis, cytotoxicity and topoisomerase II-mediated DNA cleavage intensity of the new oligosaccharide anthracyclines 1-4 modified in the sugar residue. Evaluation of cytotoxic potency on different cell lines, resulted in quite similar values among the different analogues. On the other hand, topoisomerase II-mediated DNA breaks level was different for the various compounds, and was not related to cytotoxicity, thus supporting previous observations reported for some monosaccharide anthracyclines modified in the carbohydrate portion.
