1163693-76-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1163693-76-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,6,3,6,9 and 3 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1163693-76:
(9*1)+(8*1)+(7*6)+(6*3)+(5*6)+(4*9)+(3*3)+(2*7)+(1*6)=172
172 % 10 = 2
So 1163693-76-2 is a valid CAS Registry Number.

Chemoselective chemical and electrochemical deprotections of aromatic esters

Lam, Kevin,Marko, Istvan E.

supporting information; experimental part, p. 2752 - 2755 (2009/11/30)

Alcohols can be easily and chemoselectively deprotected from the corresponding aromatic esters by using either SmI2/HMPA or by electrolysis In the presence of a proton source.

Toluates: unexpectedly versatile reagents

Lam, Kevin,Markó, István E.

supporting information; scheme or table, p. 10930 - 10940 (2010/02/28)

The mechanism of the monoelectronic reduction of aromatic esters has been investigated. The unexpected synthetic utility of the toluate moiety in the deoxygenation of alcohols and the allylation of ketones is also reported. Finally, the use of aromatic esters as robust, though easily removable, protecting groups is depicted.
