Bis-(3-chloro-propyl) sulfone, also known as 3,3'-sulfonylbispropan-1-chloro-1-ol or 3,3'-sulfonylbis(1-chloropropan-2-ol), is an organic compound with the chemical formula C6H12Cl2O3S. It is a colorless liquid with a molecular weight of 243.14 g/mol. bis-(3-chloro-propyl) sulfone is characterized by the presence of two 3-chloropropyl groups connected through a sulfone bridge, which consists of a sulfur atom double-bonded to an oxygen atom and single-bonded to another oxygen atom. Bis-(3-chloro-propyl) sulfone is used as an intermediate in the synthesis of various chemicals, including pharmaceuticals and agrochemicals, due to its reactive chloropropyl groups and sulfone functionality. It is important to handle bis-(3-chloro-propyl) sulfone with care, as it may have potential health and environmental hazards.
The CAS Registry Mumber 7767-78-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,6 and 7 respectively; the second part has 2 digits, 7 and 8 respectively. Calculate Digit Verification of CAS Registry Number 7767-78: (6*7)+(5*7)+(4*6)+(3*7)+(2*7)+(1*8)=144 144 % 10 = 4 So 7767-78-4 is a valid CAS Registry Number.
