181952-24-9 Usage
General Description
Fmoc-Tyr(SO3H)-OH is a chemical compound used in peptide synthesis. It consists of a tyrosine amino acid residue that has been modified with a sulfonic acid group, a protecting group (Fmoc), and an hydroxyl group. The sulfonic acid group adds a negative charge to the tyrosine residue, which can alter the chemical and biological properties of the peptide. The Fmoc group is used to protect the amino group of the tyrosine residue during peptide synthesis, preventing unwanted side reactions. Overall, Fmoc-Tyr(SO3H)-OH is a useful building block for the creation of peptides with modified tyrosine residues.
Check Digit Verification of cas no
The CAS Registry Mumber 181952-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,1,9,5 and 2 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 181952-24:
(8*1)+(7*8)+(6*1)+(5*9)+(4*5)+(3*2)+(2*2)+(1*4)=149
149 % 10 = 9
So 181952-24-9 is a valid CAS Registry Number.

To develop a potent and effective anti-HIV compound with a definite polyanionic structure, synthesis of oligotyrosine sulfates by oligomerization with simultaneous sulfation of tyrosine was tried. One component was successfully isolated from the mixture containing many products as its sodium salt (Y-ART-4) and was identified as the salt of nonatyrosine N- and O1-9-decasulfate, NaO3S-[Tyr(SO3Na)]9-ONa. Anti-HIV activity of Y-ART-4, determined from the protection it provided against HIV-induced cytopathic effects, was almost the same with that of dextran sulfate and curdlan sulfate.
