40993-10-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40993-10-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,9 and 3 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 40993-10:
(7*4)+(6*0)+(5*9)+(4*9)+(3*3)+(2*1)+(1*0)=120
120 % 10 = 0
So 40993-10-0 is a valid CAS Registry Number.

Synthesis and Reactivity of 3,5-Dinitrobenzoic Anhydride

Oelschlaeger, Herbert,Fritsch, Helmut

, p. 834 - 839 (1984)

3,5-Dinitrobenzoic anhydride is available from 3,5-dinitrobenzoyl chloride by limited hydrolysis in THF/pyridine.The procedure is safe and provides excellent yields.

2,6-Dimethyl-4-nitrobenzoic anhydride (DMNBA): An effective coupling reagent for the synthesis of carboxylic esters and lactones

Shiina, Isamu,Miyao, Ryo

experimental part, p. 1313 - 1328 (2009/07/05)

Various carboxylic esters are obtained at room temperature in excellent yields with high chemoselectivities from nearly equimolar amounts of carboxylic acids and alcohols using 2,6-dimethyl-4-nitrobenzoic anhydride with triethylamine by the promotion of 4-(dimethylamino)pyridine. The efficiency of the esterification is compared to those of other dehydrations using substituted benzoic anhydrides as coupling reagents. This method was successfully applied to the synthesis of threo-aleuritic acid lactone and the desired 17-membered ring compound was prepared in high yield at room temperature from the corresponding free trihydroxycarboxylic acid using 2,6-dimethyl-4-nitrobenzoic anhydride in the presence of 4-(dimethylamino)pyridine.

Dabco/SOCl2, mild, and convenient reagent for the preparation of symmetrical carboxylic acid anhydrides

Kazemi, Foad,Kiasat, Ali Reza

, p. 2287 - 2291 (2007/10/03)

Various types of carboxylic acids undergo rapid dehydration with 1,4-diazabicyclo[2.2.2]octane, dabco / thionyl chloride, under mild reaction conditions to afford symmetrical acid anhydrides in high isolated yields.
