Propanoyl chloride, also known as 3-(chlorosulfonyl)propanoyl chloride, is an organic compound with the chemical formula C3H5ClO2S. It is a colorless liquid that is soluble in organic solvents and has a pungent odor. Propanoyl chloride, 3-(chlorosulfonyl)- is primarily used as a chemical intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Propanoyl chloride is produced by the reaction of propionic acid with thionyl chloride or phosphorus pentachloride. It is a reactive compound and can undergo nucleophilic substitution reactions, making it a valuable building block in organic synthesis. Due to its reactivity, it is important to handle propanoyl chloride with care, as it can cause irritation to the eyes, skin, and respiratory system, and may also be harmful if ingested or inhaled.

Check Digit Verification of cas no

The CAS Registry Mumber 3944-67-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,4 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3944-67:
(6*3)+(5*9)+(4*4)+(3*4)+(2*6)+(1*7)=110
110 % 10 = 0
So 3944-67-0 is a valid CAS Registry Number.
