5789-21-9 Usage
General Description
Phenylthiohydantoin-threonine (PTH-threonine) is a chemical compound derived from the amino acid Threonine. It is predominantly utilized in amino acid sequencing for the identification and study of peptides and proteins. Its generation is part of the Edman degradation process, which systematically identifies amino acids in a peptide chain by producing phenylthiohydantoins. Threonine, the parent amino acid, is one of the 20 standard amino acids utilized in living organisms for protein biosynthesis. Thus, PTH-threonine plays a crucial role in analytical biochemistry and protein studies by helping scientists understand the structure, function and interaction of proteins and peptides.
Check Digit Verification of cas no
The CAS Registry Mumber 5789-21-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,8 and 9 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5789-21:
(6*5)+(5*7)+(4*8)+(3*9)+(2*2)+(1*1)=129
129 % 10 = 9
So 5789-21-9 is a valid CAS Registry Number.
