S-phenyl-DL-cysteine S,S-dioxide, also known as S-phenylcysteine sulfoxide or S-PCO, is a chemical compound derived from the amino acid cysteine. It is a chiral molecule, meaning it has two forms that are mirror images of each other (D and L isomers). The compound is characterized by the presence of a sulfur atom bonded to a phenyl group and an additional sulfur atom, forming a sulfoxide group. S-PCO is an important intermediate in the synthesis of various pharmaceuticals and agrochemicals, particularly those involving the modification of cysteine-containing peptides and proteins. It is also used in the study of protein structure and function, as well as in the development of new drugs targeting cysteine residues in proteins. The compound is synthesized through various chemical reactions, including oxidation of S-phenylcysteine with an appropriate oxidizing agent.

7554-99-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 7554-99-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,5,5 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.Calculate Digit Verification of CAS Registry Number 7554-99:
(6*7)+(5*5)+(4*5)+(3*4)+(2*9)+(1*9)=126
126 % 10 = 6
So 7554-99-6 is a valid CAS Registry Number.
