Z-Thioproline S-oxide, also known as Z-TPO, is a synthetic chemical compound with the molecular formula C9H12N2O2S. It is a derivative of proline, an amino acid, and features a sulfur atom in the form of a sulfoxide group. Z-TPO is used as a reagent in organic synthesis, particularly in the formation of cyclic sulfamidates and as a chiral auxiliary in asymmetric synthesis. It is also known for its potential applications in the development of new drugs and as a building block for the synthesis of complex organic molecules. The compound is named for its protecting group, the benzyloxycarbonyl (Z) group, which is used to shield the thiol group during chemical reactions, and its sulfoxide functionality, which is an oxidized form of a sulfide.
The CAS Registry Mumber 65663-71-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,6,6 and 3 respectively; the second part has 2 digits, 7 and 1 respectively. Calculate Digit Verification of CAS Registry Number 65663-71: (7*6)+(6*5)+(5*6)+(4*6)+(3*3)+(2*7)+(1*1)=150 150 % 10 = 0 So 65663-71-0 is a valid CAS Registry Number.
