Check Digit Verification of cas no

The CAS Registry Mumber 721959-05-3 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, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 721959-05:
(8*7)+(7*2)+(6*1)+(5*9)+(4*5)+(3*9)+(2*0)+(1*5)=173
173 % 10 = 3
So 721959-05-3 is a valid CAS Registry Number.

New analogues of the potent cytotoxic saponin OSW-1

Wojtkielewicz, Agnieszka,D?ugosz, Maciej,Maj, Jadwiga,Morzycki, Jacek W.,Nowakowski, Micha?,Renkiewicz, Joanna,Strnad, Miroslav,Swaczynová, Jana,Wilczewska, Agnieszka Z.,Wójcik, Jacek

, p. 3667 - 3673 (2008/02/09)

Saponin OSW-1 (5e-G2; 3β,16β,17α-trihydroxycholest-5-en-22- one 16-O-{O-[2-O-(4-methoxybenzoyl)-β-D-xylopyranosyl]-(1→3)-2-O- acetyl-α-arabinopyranoside}) analogues: with modified side chain (5a/d-G2), 22-deoxo-23,24,25,26,27-pentanor- (14), 22-deoxo-23-o

Synthesis of analogues of a potent antitumor saponin OSW-1

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

, p. 3323 - 3326 (2007/10/03)

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.
