Troc-L-Ser(OCH2C6H5)-ODpm, also known as 2-(9H-fluoren-9-ylmethoxycarbonyl)-3-phenyl-L-serine, is a complex organic compound that serves as a protecting group in peptide synthesis. It is a derivative of L-serine, an amino acid, with a Tropane (Troc) protecting group and a 9-fluorenylmethoxycarbonyl (Fmoc) protecting group. The Tropane group is used to protect the amino group, while the Fmoc group protects the carboxylic acid group. Additionally, it has a phenyl group attached to the serine's side chain, which can influence the properties of the peptide. Troc-L-Ser(OCH2C6H5)-ODpm is crucial in the synthesis of peptides and proteins, as it allows for the stepwise assembly of amino acids while preventing unwanted side reactions. The Tropane and Fmoc groups can be selectively removed at different stages of the synthesis process, enabling the controlled formation of the desired peptide sequence.
The CAS Registry Mumber 98694-90-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,6,9 and 4 respectively; the second part has 2 digits, 9 and 0 respectively. Calculate Digit Verification of CAS Registry Number 98694-90: (7*9)+(6*8)+(5*6)+(4*9)+(3*4)+(2*9)+(1*0)=207 207 % 10 = 7 So 98694-90-7 is a valid CAS Registry Number.
