15756-15-7 Usage
Description
(~195~Hg)Mercury, also known as elemental mercury, is a heavy, silvery transition metal with the atomic number 80 and the symbol Hg. It is the only metallic element that is liquid at standard conditions for temperature and pressure, characterized by its high density and low freezing point.
Uses
Used in Scientific Instruments:
(~195~Hg)Mercury is used as a component in thermometers and barometers for its unique liquid state at room temperature, allowing it to expand and contract with changes in temperature and pressure.
Used in Industrial Processes:
(~195~Hg)Mercury is utilized in various industrial applications, such as the production of certain types of batteries, electrical switches, and fluorescent lamps, due to its electrical conductivity and chemical properties.
However, it is important to note that mercury is a toxic substance, and its use is becoming increasingly restricted due to the serious health issues it can cause, including neurological and behavioral disorders. Efforts to reduce mercury pollution and promote safer alternatives are ongoing to protect human health and the environment.
Check Digit Verification of cas no
The CAS Registry Mumber 15756-15-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,7,5 and 6 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 15756-15:
(7*1)+(6*5)+(5*7)+(4*5)+(3*6)+(2*1)+(1*5)=117
117 % 10 = 7
So 15756-15-7 is a valid CAS Registry Number.
