125612-26-2 Usage
General Description
Coal is a complex mixture of organic and inorganic compounds, primarily consisting of carbon, hydrogen, oxygen, sulfur, and nitrogen. It also contains various volatile organic compounds, heavy metals, and other trace elements. The composition of coal varies depending on the type and source, such as bituminous, anthracite, and lignite, with different ratios of carbon and impurities. When burned, coal releases greenhouse gases, such as carbon dioxide and methane, as well as sulfur dioxide, nitrogen oxides, and other pollutants that contribute to air pollution and climate change. Additionally, coal combustion byproducts can contaminate soil and water, posing environmental and health risks. Despite its drawbacks, coal is still a major source of energy for electricity generation and industrial processes worldwide.
Check Digit Verification of cas no
The CAS Registry Mumber 125612-26-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,5,6,1 and 2 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 125612-26:
(8*1)+(7*2)+(6*5)+(5*6)+(4*1)+(3*2)+(2*2)+(1*6)=102
102 % 10 = 2
