(+/-)-N-Trityl-alanin-<2-methylmercapto-ethylester> is a complex organic compound with the molecular formula C23H25NO2S. It is a derivative of alanine, an amino acid, where the alanine's nitrogen atom is protected by a trityl group (a phenylmethyl group), and the carboxylic acid group is esterified with a 2-methylmercapto-ethyl group. (+/-)-N-Trityl-alanin-<2-methylmercapto-ethylester> is often used in peptide synthesis as a protected amino acid, allowing for the controlled formation of peptide bonds in the presence of other functional groups. The trityl group serves as a protecting group for the nitrogen, preventing unwanted side reactions, while the 2-methylmercapto-ethylester group protects the carboxylic acid, facilitating controlled deprotection steps in peptide synthesis.
The CAS Registry Mumber 5879-44-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,7 and 9 respectively; the second part has 2 digits, 4 and 4 respectively. Calculate Digit Verification of CAS Registry Number 5879-44: (6*5)+(5*8)+(4*7)+(3*9)+(2*4)+(1*4)=137 137 % 10 = 7 So 5879-44-7 is a valid CAS Registry Number.
