Check Digit Verification of cas no

The CAS Registry Mumber 219906-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,9,0 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 219906-45:
(8*2)+(7*1)+(6*9)+(5*9)+(4*0)+(3*6)+(2*4)+(1*5)=153
153 % 10 = 3
So 219906-45-3 is a valid CAS Registry Number.

First total synthesis of an exceptionally potent antitumor saponin, OSW- 1

Deng, Shaojiang,Yu, Biao,Lou, Yun,Hui, Yongzheng

, p. 202 - 208 (2007/10/03)

OSW-1 (1), an acylated disaccharide cholestane saponin from Ornithogalum saudersiae with exceptionally potent antitumor activity, was first synthesized from commercially available dehydroisoandrosterone, L-arabinose, and D-xylose in total 27 steps with the longest linear sequence of 14 steps and in 6% yield.
