Diichloroacetonitrile, also known as dichloroacetonitrile or DCAN, is an organic compound with the chemical formula C2HCl2N. It is a colorless, toxic liquid that is soluble in water and various organic solvents. DCAN is primarily used as an intermediate in the production of various chemicals, including pharmaceuticals, agrochemicals, and dyes. It is synthesized through the reaction of chloroacetonitrile with chlorine gas. Due to its toxicity and potential to form hazardous byproducts, such as hydrogen cyanide, DCAN is considered a hazardous substance and requires proper handling and disposal.
The CAS Registry Mumber 870-67-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,7 and 0 respectively; the second part has 2 digits, 6 and 7 respectively. Calculate Digit Verification of CAS Registry Number 870-67: (5*8)+(4*7)+(3*0)+(2*6)+(1*7)=87 87 % 10 = 7 So 870-67-7 is a valid CAS Registry Number.
