5789-24-2 Usage
General Description
Phenylthiohydantoin-tryptophan is a chemical compound used in the process of sequencing proteins. It is formed by the reaction of phenylisothiocyanate with tryptophan, resulting in the formation of a phenylthiohydantoin derivative of tryptophan. PHENYLTHIOHYDANTOIN-TRYPTOPHAN is used in the Edman degradation method, a technique for determining the sequence of amino acids in a protein. It works by cleaving the N-terminal amino acid and converting it into a derivative that can be identified and analyzed. Phenylthiohydantoin-tryptophan plays a crucial role in protein sequencing and has applications in biochemistry and pharmaceutical research.
Check Digit Verification of cas no
The CAS Registry Mumber 5789-24-2 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 4 respectively.
Calculate Digit Verification of CAS Registry Number 5789-24:
(6*5)+(5*7)+(4*8)+(3*9)+(2*2)+(1*4)=132
132 % 10 = 2
So 5789-24-2 is a valid CAS Registry Number.
