24302-23-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 24302-23-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,3,0 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 24302-23:
(7*2)+(6*4)+(5*3)+(4*0)+(3*2)+(2*2)+(1*3)=66
66 % 10 = 6
So 24302-23-6 is a valid CAS Registry Number.

An efficient procedure for the 1,3-transposition of allylic alcohols based on lithium naphthalenide induced reductive elimination of epoxy mesylates

Wu, Yen-Ku,Liu, Hsing-Jang,Zhu, Jia-Liang

, p. 621 - 623 (2008/12/22)

An efficient protocol for the 1,3-transposition of allylic alcohols has been developed. The method is based on the pretransformation of allylic alcohols into the corresponding epoxy mesylates, followed by the reductive elimination of the resulting epoxy mesylates by using lithium naphthalenide (LN) as a reducing agent.

A convergent synthesis of the spiroketal moiety of the HIV-1 protease inhibitors didemnaketals

Jia, Yan Xing,Li, Xin,Wu, Bin,Zhao, Xue Zhi,Tu, Yong Qiang

, p. 1697 - 1708 (2007/10/03)

The stereoselective synthesis of the spiroketal fragment 4a and its C1″-epimer 4b of the HIV-1 protease inhibitors didemnaketals has been carried out through multisteps from the natural (R)-(+)-pulegone, which involved the diastereoselective construction of four chiral carbon centers by intramolecular chiral induction.
