Acetylene, with the chemical formula C2H2, is a colorless, highly flammable gas that is the simplest alkyne. It is produced through various methods, including the reaction of calcium carbide with water. Acetylene is known for its triple bond between the two carbon atoms, which gives it unique chemical properties. It is widely used in the production of chemicals, such as acetylene black, vinyl chloride, and polyvinyl chloride. Additionally, it is used as a fuel in welding and cutting metals due to its high flame temperature. Acetylene is also a key component in the synthesis of various organic compounds and has applications in the pharmaceutical and chemical industries.
The CAS Registry Mumber 2724-54-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,2 and 4 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 2724-54: (6*2)+(5*7)+(4*2)+(3*4)+(2*5)+(1*4)=81 81 % 10 = 1 So 2724-54-1 is a valid CAS Registry Number.
