26623-59-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 26623-59-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,6,2 and 3 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 26623-59:
(7*2)+(6*6)+(5*6)+(4*2)+(3*3)+(2*5)+(1*9)=116
116 % 10 = 6
So 26623-59-6 is a valid CAS Registry Number.

Phase transfer catalysis by tetraethylammonium bromide: Nucleophilic opening of anhydrides using potassium superoxide in aprotic medium

Singh, Sundaram,Shukla, Ajay Kumar,Singh, Krishna Nand

, p. 1184 - 1188 (2007/10/03)

Tetraethylammonium superoxide, generated in situ by the phase transfer reaction of potassium superoxide and tetraethylammonium bromide, brings about a clean cleavage of various anhydrides, particularly those with high molecular weight in dry dimethylformamide. As an outcome, succinic anhydride 1; glutaric anhydride 2; 3,3-dimethylglutaric anhydride 3; phthalic anhydride 4; diphenic anhydride 5; 1,2,3,4-tetrahydro-9-oxo-1,4-ethanonaphthalene-2,3- endo-dicarboxylic anhydride 6: 1,4,5,6,7,7-hexachloro-5-norbomene-2,3- dicarboxylic anhydride 7; endo-bicyclo [2.2.1] heptan-2-one-5,6-dicarboxylic anhydride 8; cis-5-norbornene-endo-2,3-dicarboxylic anhydride 9 and trans- 1,2-cyclohexane dicarboxylic anhydride 10 have been transformed into their corresponding dicarboxylic acids in fairly good yields. The report demonstrates the applicability of tetraethylammonium bromide as a phase transfer catalyst for efficient superoxide studies.
