N,N'-Bis-benzyloxycarbonyl-L-cystinyl-bis-cyanomethylester is a complex organic compound with the chemical formula C26H26N2O6S2. It is a derivative of the amino acid cysteine, where two cysteine molecules are linked by a disulfide bond, forming a cystine structure. The compound is protected with benzyloxycarbonyl (Z) groups, which are commonly used in peptide synthesis to prevent unwanted side reactions. Additionally, it features cyanomethyl ester groups, which can be used for further functionalization or as a protecting group. N,N'-Bis-benzyloxycarbonyl-L-cystinyl-bis-cyanomethylester is primarily used in the synthesis of peptides and proteins, where the Z groups and cyanomethyl esters help control the reactivity and selectivity of the cysteine residues, facilitating the formation of specific disulfide bonds in the final protein product.
The CAS Registry Mumber 4703-45-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 3 respectively; the second part has 2 digits, 4 and 5 respectively. Calculate Digit Verification of CAS Registry Number 4703-45: (6*4)+(5*7)+(4*0)+(3*3)+(2*4)+(1*5)=81 81 % 10 = 1 So 4703-45-1 is a valid CAS Registry Number.
