Fuel gases, specifically water gas, are a type of chemical compound primarily produced through the reaction of steam and carbon, such as coal or coke, at high temperatures. This process, known as gasification, generates a mixture of gases, including hydrogen, carbon monoxide, and small amounts of carbon dioxide and methane. Water gas is widely used as a fuel source in various industrial applications, such as steel production and power generation, due to its high energy content and ability to be easily transported through pipelines. Additionally, it serves as a valuable feedstock for the synthesis of chemicals like ammonia and methanol. However, it is essential to manage and handle water gas safely, as it is flammable and can pose health and environmental risks if not properly controlled.
The CAS Registry Mumber 8021-92-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,2 and 1 respectively; the second part has 2 digits, 9 and 2 respectively. Calculate Digit Verification of CAS Registry Number 8021-92: (6*8)+(5*0)+(4*2)+(3*1)+(2*9)+(1*2)=79 79 % 10 = 9 So 8021-92-9 is a valid CAS Registry Number.
