2-Butynyl chloride, also known as 2-butyn-1-yl chloride or 4-chloro-1-butyne, is a colorless liquid with the chemical formula C4H5Cl. It is an organic compound that belongs to the family of alkynyl halides, characterized by the presence of a triple bond (C≡C) and a chlorine atom. This chemical is primarily used as an intermediate in the synthesis of various organic compounds, such as pharmaceuticals, agrochemicals, and specialty chemicals. Due to its reactivity, 2-butynyl chloride is sensitive to heat, light, and moisture, and requires careful handling and storage. It is also considered a hazardous substance, with potential health risks including irritation to the eyes, skin, and respiratory system, as well as being harmful if swallowed.

3355-17-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3355-17-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,5 and 5 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3355-17:
(6*3)+(5*3)+(4*5)+(3*5)+(2*1)+(1*7)=77
77 % 10 = 7
So 3355-17-7 is a valid CAS Registry Number.
