Erythro-3,3'-dimethyl-D-cystine is a synthetic, non-natural amino acid derivative characterized by the presence of two methyl groups attached to the 3rd carbon of each cysteine molecule. It is a diastereomer of the naturally occurring L-cystine, which means it has the same molecular formula but a different spatial arrangement of atoms. erythro-3,3'-dimethyl-D-cystine is known for its potential use in the synthesis of various pharmaceuticals and biologically active molecules, as well as in research studies exploring the properties of non-natural amino acids. Due to its unique structure, erythro-3,3'-dimethyl-D-cystine can provide insights into the behavior of proteins and peptides containing non-natural amino acids, contributing to the understanding of their interactions and functions in biological systems.
The CAS Registry Mumber 6700-06-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,0 and 0 respectively; the second part has 2 digits, 0 and 6 respectively. Calculate Digit Verification of CAS Registry Number 6700-06: (6*6)+(5*7)+(4*0)+(3*0)+(2*0)+(1*6)=77 77 % 10 = 7 So 6700-06-7 is a valid CAS Registry Number.
