13981-43-6 Usage

Uses

Used in Geology:
Chlorine-36 is used as a dating tool in geology for determining the age of groundwater and ice cores. Its radioactive nature allows scientists to measure the time elapsed since the water or ice was last exposed to the atmosphere, providing valuable information about past climate conditions and water circulation patterns.
Used in Nuclear Power Generation:
Chlorine-36 is utilized in nuclear power generation as a byproduct of nuclear reactions. It can be extracted and used as a radioactive tracer to monitor the movement of water in the environment, helping to assess the safety and efficiency of nuclear power plants.
Used in Production of Radiopharmaceuticals:
Chlorine-36 is employed in the production of radiopharmaceuticals, which are used for diagnostic and therapeutic purposes in medicine. Its radioactive properties enable the development of compounds that can be used to visualize and treat various medical conditions, such as cancer and cardiovascular diseases.
Used in Environmental Research:
Chlorine-36 is used as a tracer in environmental research to study the movement and distribution of water in ecosystems. By tracking the isotope, scientists can gain insights into the hydrological cycle, water pollution, and the impact of human activities on the environment.
However, due to its radioactive nature, Chlorine-36 poses potential health risks and requires careful handling and disposal to ensure the safety of individuals and the environment.

Check Digit Verification of cas no

The CAS Registry Mumber 13981-43-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,9,8 and 1 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 13981-43:
(7*1)+(6*3)+(5*9)+(4*8)+(3*1)+(2*4)+(1*3)=116
116 % 10 = 6
So 13981-43-6 is a valid CAS Registry Number.
