835-24-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 835-24-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,3 and 5 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 835-24:
(5*8)+(4*3)+(3*5)+(2*2)+(1*4)=75
75 % 10 = 5
So 835-24-5 is a valid CAS Registry Number.

An Au-Catalyzed Cyclialkylation of Electron-Rich Arenes with Epoxides to Prepare 3-Chromanols

Shi, Zhangjie,He, Chuan

, p. 5964 - 5965 (2004)

A gold-catalyzed cyclialkylation of electron-rich arenes with tethered epoxides afforded 3-chromanols stereospecifically. Copyright

Friedel-Crafts alkylation of arenes with epoxides promoted by fluorinated alcohols or water

Li, Guo-Xing,Qu, Jin

supporting information; experimental part, p. 2653 - 2655 (2010/07/08)

The stereoselective intra- and intermolecular Friedel-Crafts alkylation of electron-rich arenes with epoxides can take place in refluxing 1,1,1,3,3,3-hexafluoroisopropanol owing to its weak acidity and high ionizing power.
