Carbon iodide (CI2), also known as diiodomethane, is a chemical compound with the formula CH2I2. It is a colorless, volatile, and toxic liquid at room temperature, with a pungent odor. CI2 is a halogenated hydrocarbon, which means it contains carbon, hydrogen, and iodine atoms. It is synthesized by reacting methane with iodine under UV light or through the reaction of methyl iodide with iodine. Carbon iodide has various applications, including as a chemical intermediate in the production of pharmaceuticals, agrochemicals, and other organic compounds. Due to its reactivity and potential health risks, it is essential to handle CI2 with proper safety measures and precautions.
The CAS Registry Mumber 4371-79-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,3,7 and 1 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 4371-79: (6*4)+(5*3)+(4*7)+(3*1)+(2*7)+(1*9)=93 93 % 10 = 3 So 4371-79-3 is a valid CAS Registry Number.
