Check Digit Verification of cas no

The CAS Registry Mumber 721959-20-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,2,1,9,5 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 721959-20:
(8*7)+(7*2)+(6*1)+(5*9)+(4*5)+(3*9)+(2*2)+(1*0)=172
172 % 10 = 2
So 721959-20-2 is a valid CAS Registry Number.

Synthesis of analogues of a potent antitumor saponin OSW-1

Morzycki, Jacek W.,Wojtkielewicz, Agnieszka,Wolczynski, Slawomir

, p. 3323 - 3326 (2004)

A series of side chain analogues (5a-e), a 22-glycosylated isomer (10), and 16β-O-L-arabinosyl (13a) or 16β-O-D-xylosyl (13b) analogues of OSW-1 were synthesized. All analogues were found to be less cytotoxic against breast and endometrial cancer cell lines than the natural product.
