"O,O'--diglycolsaeure-bis-(4-nitro-benzylester)" is a complex organic compound with the chemical formula C40H34N2O14S2. It is a derivative of diglycolic acid, featuring a bis-benzyloxycarbonyl-L-cystidyl group, which is a protected form of cysteine, an amino acid. The compound is characterized by two benzyloxycarbonyl groups that protect the amino and carboxylic acid groups of the cysteine, and two 4-nitro-benzyl ester groups that are attached to the diglycolic acid moiety. This structure is significant in peptide synthesis, where it serves as a protected building block, allowing for the controlled formation of peptide bonds. The compound's complexity and specific functional groups make it a valuable tool in the synthesis of larger peptide structures, particularly in the pharmaceutical and biotechnology industries.
The CAS Registry Mumber 2748-00-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,4 and 8 respectively; the second part has 2 digits, 0 and 0 respectively. Calculate Digit Verification of CAS Registry Number 2748-00: (6*2)+(5*7)+(4*4)+(3*8)+(2*0)+(1*0)=87 87 % 10 = 7 So 2748-00-7 is a valid CAS Registry Number.
