[1,2']Binaphthyl-2,3-dicarboxylic acid-anhydride is a complex organic compound with the molecular formula C22H12O3. It is derived from binaphthyl, a chiral molecule consisting of two naphthalene rings joined at opposite positions (1 and 2' positions). The term "dicarboxylic acid-anhydride" indicates that the compound has two carboxylic acid groups that are connected through an anhydride bridge, which is a carbonyl group (C=O) that links the two carboxylic acid groups. This specific structure endows the compound with unique chemical properties and reactivity, making it a valuable intermediate in the synthesis of various chiral ligands and catalysts used in asymmetric synthesis. The anhydride form of the compound is particularly useful for forming esters and amides, which are essential in the preparation of enantioselective catalysts.

4444-28-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4444-28-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,4 and 4 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4444-28:
(6*4)+(5*4)+(4*4)+(3*4)+(2*2)+(1*8)=84
84 % 10 = 4
So 4444-28-4 is a valid CAS Registry Number.
