Tyrosine dianion is a chemical species derived from the amino acid tyrosine, which plays a crucial role in various biological processes. In its dianionic form, tyrosine has two negatively charged groups, resulting from the deprotonation of two acidic hydrogen atoms. This form is particularly relevant in enzymatic reactions, such as those catalyzed by tyrosinase, where the dianion acts as a substrate. Tyrosine dianion is also involved in the synthesis of important biomolecules like melanin, thyroid hormones, and certain neurotransmitters. Its chemical structure, with a phenolic hydroxyl group and an aromatic ring, makes it a key component in various metabolic pathways and a subject of interest in fields such as biochemistry and medicine.
The CAS Registry Mumber 26302-79-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,3,0 and 2 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 26302-79: (7*2)+(6*6)+(5*3)+(4*0)+(3*2)+(2*7)+(1*9)=94 94 % 10 = 4 So 26302-79-4 is a valid CAS Registry Number.
