129521-66-0 Usage
General Description
Lignite, also known as brown coal, is a type of coal that is low in carbon and high in moisture. It is a soft, brownish-black sedimentary rock that is formed from peat under relatively low pressure and temperature. Lignite is often used as a fuel for electricity generation due to its relatively high energy content and abundance. However, it is also known for its high moisture content, which makes it less energy-dense and more difficult to transport and store compared to other coal types. Lignite also contains a higher percentage of impurities, such as sulfur and ash, which can contribute to environmental pollution when burned. Despite these drawbacks, lignite remains an important source of energy in certain regions, particularly in countries with large reserves of this type of coal.
Check Digit Verification of cas no
The CAS Registry Mumber 129521-66-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,5,2 and 1 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129521-66:
(8*1)+(7*2)+(6*9)+(5*5)+(4*2)+(3*1)+(2*6)+(1*6)=130
130 % 10 = 0
So 129521-66-0 is a valid CAS Registry Number.
