β-(DL-N-Tosyl-β-phenylalanylamino)-propionitril is a complex organic compound with the chemical formula C17H16N2O3S. It is a derivative of phenylalanine, an essential amino acid, with a tosyl group (tosyl = 4-methylbenzenesulfonyl) attached to the nitrogen atom and a propionitril group (cyanoethyl) attached to the β-carbon. β-(DL-N-Tosyl-β-phenylalanylamino)-propionitril is often used in peptide synthesis and as a protecting group in organic chemistry, particularly in the synthesis of peptides and other biomolecules. Its structure provides a stable and easily removable protecting group, which is crucial for the selective synthesis of complex molecules. The compound's name reflects its structure, indicating the presence of a tosyl group, a phenylalanine residue, and a propionitril group.
The CAS Registry Mumber 17086-85-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,0,8 and 6 respectively; the second part has 2 digits, 8 and 5 respectively. Calculate Digit Verification of CAS Registry Number 17086-85: (7*1)+(6*7)+(5*0)+(4*8)+(3*6)+(2*8)+(1*5)=120 120 % 10 = 0 So 17086-85-0 is a valid CAS Registry Number.
