Thyroxine, also known as tetraiodothyronine or T4, is a crucial hormone produced by the thyroid gland, which plays a significant role in regulating the body's metabolism. It is a derivative of the amino acid tyrosine, containing four iodine atoms, and is synthesized by the coupling of two molecules of the thyroid hormone precursor, diiodotyrosine. Thyroxine is essential for various physiological processes, including growth, development, and energy production, and it influences the function of almost every organ system in the body. The hormone is transported in the bloodstream, bound to proteins, and converted to its active form, triiodothyronine (T3), in the peripheral tissues. Any imbalance in thyroxine levels can lead to various health issues, such as hypothyroidism or hyperthyroidism, highlighting its importance in maintaining overall well-being.

Check Digit Verification of cas no

The CAS Registry Mumber 299-80-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,9 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 299-80:
(5*2)+(4*9)+(3*9)+(2*8)+(1*0)=89
89 % 10 = 9
So 299-80-9 is a valid CAS Registry Number.
