1,1,1-Trichloroethane, also known as methyl chloroform, is a colorless, volatile liquid with a chloroform-like odor. It is an organic compound with the chemical formula C2H3Cl3, consisting of an ethane molecule with three hydrogen atoms replaced by chlorine atoms. This chlorinated hydrocarbon was widely used as a solvent, degreaser, and refrigerant due to its ability to dissolve grease and oil. However, its production and use have been phased out in many countries due to its ozone-depleting properties and potential health risks, as it is classified as a hazardous air pollutant and a probable human carcinogen.
The CAS Registry Mumber 3922-25-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,2 and 2 respectively; the second part has 2 digits, 2 and 5 respectively. Calculate Digit Verification of CAS Registry Number 3922-25: (6*3)+(5*9)+(4*2)+(3*2)+(2*2)+(1*5)=86 86 % 10 = 6 So 3922-25-6 is a valid CAS Registry Number.
