Check Digit Verification of cas no

The CAS Registry Mumber 321125-08-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,1,2 and 5 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 321125-08:
(8*3)+(7*2)+(6*1)+(5*1)+(4*2)+(3*5)+(2*0)+(1*8)=80
80 % 10 = 0
So 321125-08-0 is a valid CAS Registry Number.

Synthesis, conformational analysis and SAR research of OSW-1 analogues

Liu, Chao,Wang, A-peng,Jin, Longlong,Guo, Yanshen,Li, Yan,Zhao, Zhehui,Lei, Pingsheng

, p. 4091 - 4102 (2016/07/06)

A series of novel OSW-1 analogues were synthesized by coupling disaccharides (2-O-4-methoxylbenzoyl-β-D-xylopyranosyl-(1→3)-2-O-acetyl-α-L-arabinopyranosyl) or (2-O-4-(E)-cinnamoyl-β-D-xylopyranosyl-(1→3)-2-O-acetyl-α-L-arabinopyranosyl) and their 1→4 lin

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.
