123731-52-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 123731-52-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,7,3 and 1 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 123731-52:
(8*1)+(7*2)+(6*3)+(5*7)+(4*3)+(3*1)+(2*5)+(1*2)=102
102 % 10 = 2
So 123731-52-2 is a valid CAS Registry Number.

Dithioacetalization or thioetherification of benzyl alcohols using 9-mesityl-10-methylacridinium perchlorate photocatalyst

Pramanik, Milan,Choudhuri, Khokan,Mathuri, Ashis,Mal, Prasenjit

supporting information, p. 10211 - 10214 (2020/09/21)

We report herein the use of 9-mesityl-10-methylacridinium perchlorate as the visible-light photocatalyst for dithioacetalization or thioetherification of benzyl alcohols in one pot using aerial dioxygen as a terminal oxidant. EPR analysis and Stern-Volmer

Lewis acid assisted permanganate oxidations

Lai, Sheng,Lee, Donald G.

, p. 9879 - 9887 (2007/10/03)

Lewis acids combine with permanganate in acetone solutions to form a complex that has enhanced oxidizing capabilities. The use of Lewis acids under these conditions to promote permanganate oxidations is superior to the use of Bronsted acids because the latter promote enolization of the solvent and subsequent unproductive reduction of the oxidant. The products obtained from a variety of alkenes, alkynes, arenes, sulfides, alcohols and ethers have been identified and probable reaction mechanisms proposed.
