Propyl alcohol, also known as 1-propanol or n-propanol, is a colorless, flammable liquid with a distinctive alcoholic odor. It is a primary alcohol with the chemical formula C3H8O, consisting of three carbon atoms, eight hydrogen atoms, and one oxygen atom. Propyl alcohol is widely used in various industries, including pharmaceuticals, cosmetics, and cleaning products, as a solvent, disinfectant, and antifreeze. It is also used as a fuel in certain types of camping stoves and as a component in the production of other chemicals. Propyl alcohol is derived from petrochemicals or through the fermentation of grains, and it is considered less toxic than other alcohols like methanol and ethanol, but it can still cause health issues if ingested or inhaled in large quantities.
The CAS Registry Mumber 71-31-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 1 respectively; the second part has 2 digits, 3 and 1 respectively. Calculate Digit Verification of CAS Registry Number 71-31: (4*7)+(3*1)+(2*3)+(1*1)=38 38 % 10 = 8 So 71-31-8 is a valid CAS Registry Number.
