324740-33-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 324740-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,4,7,4 and 0 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 324740-33:
(8*3)+(7*2)+(6*4)+(5*7)+(4*4)+(3*0)+(2*3)+(1*3)=122
122 % 10 = 2
So 324740-33-2 is a valid CAS Registry Number.

Chemical intertransformations of diverse bisdesmosidic furostanol saponins

Zhao, Dong-Mei,Liu, Yang,Liu, Yong-Xiang,Zheng, Li-Gang,Yan, Mao-Cai,Cheng, Mao-Sheng

, p. 214 - 215 (2008/02/04)

An effective synthetic route towards four types of bisdesmosidic furostanol saponin was developed and 36 derivatives were designed and synthesized for antitumor investigation. The chemical intertransformations of these furostanol structures were discussed

The first synthetic route to furostan saponins

Yu, Biao,Liao, Jianchun,Zhang, Jianbo,Hui, Yongzheng

, p. 77 - 79 (2007/10/03)

26-O-β-D-Glucopyranosyl-22-methoxy-25(R)-furost-5-en-3β-ol 3-O-β-D-glucopyranoside is synthesized from diosgenin in 11 steps and 26% overall yield. The present synthetic route represents the first one to furostan saponins.
