(2R,3R)-2-Benzyloxy-3-hydroxy-2-methyl-4-phenyl-pentanoic acid 2,6-di-tert-butyl-4-methyl-phenyl ester is a complex organic compound with a molecular formula of C30H38O4. It is a chiral molecule, meaning it has a non-superimposable mirror image, with the R configuration at both the 2nd and 3rd carbon atoms. The compound features a pentanoic acid backbone with a benzyloxy group at the 2nd carbon, a hydroxyl group at the 3rd carbon, and a methyl group at the 2nd carbon. The 4th carbon is bonded to a phenyl ring, and the 5th carbon is a terminal carboxylic acid group. This carboxylic acid group is esterified with a 2,6-di-tert-butyl-4-methyl-phenol, which is a bulky, electron-donating group that can influence the compound's reactivity and stability. This ester is a derivative of a pentanoic acid and is characterized by its specific stereochemistry and functional groups, which can be relevant in various chemical and pharmaceutical applications.
The CAS Registry Mumber 78957-76-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,9,5 and 7 respectively; the second part has 2 digits, 7 and 6 respectively. Calculate Digit Verification of CAS Registry Number 78957-76: (7*7)+(6*8)+(5*9)+(4*5)+(3*7)+(2*7)+(1*6)=203 203 % 10 = 3 So 78957-76-3 is a valid CAS Registry Number.
