Dicyclohexylmethoxycarbonyl-glycinaethylester, also known as DCM-Gly-OEt, is a chemical compound with the molecular formula C19H31NO4. It is a derivative of glycine, an amino acid, and is characterized by the presence of a dicyclohexylmethoxycarbonyl (DCM) group, which serves as a protecting group for the amino group, and an ethyl ester group. Dicyclohexylmethoxycarbonyl-glycinaethylester is often used in peptide synthesis as a building block, where the DCM group protects the amino group from unwanted reactions until it is specifically removed at a later stage in the synthesis process. The ethyl ester group is a common esterification of the carboxylic acid group, which can be hydrolyzed under basic conditions to yield the free acid form of the peptide. DCM-Gly-OEt is a valuable component in the field of organic chemistry and pharmaceuticals, particularly in the synthesis of complex peptide structures.
The CAS Registry Mumber 7738-70-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,3 and 8 respectively; the second part has 2 digits, 7 and 0 respectively. Calculate Digit Verification of CAS Registry Number 7738-70: (6*7)+(5*7)+(4*3)+(3*8)+(2*7)+(1*0)=127 127 % 10 = 7 So 7738-70-7 is a valid CAS Registry Number.
