5-Benzyloxy-[1,3,4]oxadiazole-2,3-dicarboxylic acid 3-benzyl ester 2-ethyl ester is a complex organic compound with the molecular formula C20H15N2O6. It is a derivative of oxadiazole, a five-membered heterocyclic ring containing two nitrogen atoms and one oxygen atom. This specific compound features a benzyloxy group attached to the 5-position of the oxadiazole ring, and two carboxylic acid groups at the 2 and 3 positions. The 3-carboxylic acid group is further esterified with a benzyl group, while the 2-carboxylic acid group is esterified with an ethyl group. This molecule is of interest in the field of organic chemistry and material science, particularly for its potential applications in the synthesis of pharmaceuticals, dyes, and other specialty chemicals.
The CAS Registry Mumber 5321-35-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,2 and 1 respectively; the second part has 2 digits, 3 and 5 respectively. Calculate Digit Verification of CAS Registry Number 5321-35: (6*5)+(5*3)+(4*2)+(3*1)+(2*3)+(1*5)=67 67 % 10 = 7 So 5321-35-7 is a valid CAS Registry Number.
