6093-29-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6093-29-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,9 and 3 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 6093-29:
(6*6)+(5*0)+(4*9)+(3*3)+(2*2)+(1*9)=94
94 % 10 = 4
So 6093-29-4 is a valid CAS Registry Number.

Sterically Hindered Carboxylic Acid Esters

Bagal,Ishchenko,Nikolaev

, p. 1731 - 1738 (2007/10/03)

Methods have been developed for preparation of esters formed by sterically hindered benzoic acids and various alcohols, which were difficult to obtain previously. The methods are based on the reaction of carbenium ions, generated from primary aliphatic N-nitroamines by the action of nitrous acid or Lewis acids, with carboxylic acid at the sterically accessible oxygen atom of the carboxy group. Reactions of nitrobenzoic acids and benzenepolycarboxylic acids with 2,2,2-trinitroethyl hydrogen sulfate provide an effective method for preparation of corresponding trinitroethyl esters.
