Astatine, a radioactive halogen element, is the heaviest among the halogens and is characterized by its short half-lives and instability. It is one of the rarest elements in nature, with only trace amounts of its short-lived isotopes found in equilibrium with uranium, neptunium, and thorium isotopes. Astatine is volatile and can be distilled in a vacuum at room temperature, exhibiting solubility in various organic solvents and likely low solubility in water.

7440-68-8 Usage

Uses

1. Used in Medical Applications:
Astatine is used as a potential medical application due to its radioactive properties and ability to concentrate in the thyroid gland. The element's radioactivity allows for its use in targeted therapies, such as cancer treatment, where it can be employed to deliver focused radiation doses to specific tissues or cells.
2. Used in Research and Development:
Astatine's unique properties and rarity make it an interesting subject for research and development in various scientific fields. Its radioactivity and behavior as a halogen can provide insights into the properties of other elements and contribute to the understanding of atomic structure and behavior.

Hazard

Exposure to radiation may cause cancer. Studies on experimental animals show it induces tumors.

Check Digit Verification of cas no

The CAS Registry Mumber 7440-68-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,4 and 0 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 7440-68:
(6*7)+(5*4)+(4*4)+(3*0)+(2*6)+(1*8)=98
98 % 10 = 8
So 7440-68-8 is a valid CAS Registry Number.
