Calculate Digit Verification of CAS Registry Number 1449432-43:
(9*1)+(8*4)+(7*4)+(6*9)+(5*4)+(4*3)+(3*2)+(2*4)+(1*3)=172
172 % 10 = 2
So 1449432-43-2 is a valid CAS Registry Number.

Simplified des-AB-type aglycone of antitumor steroidal saponin OSW-1 was concisely prepared starting from readily available Hajos ketone. We further completed the synthesis of des-AB-OSW-1 analogue by the installation of the disaccharide moiety into the des-AB aglycone, and evaluated its antitumor activity. The results indicated that a truncated aglycone drug design strategy based on OSW-1 would be a promising approach for the development of novel antitumor agents.
