2-Chloroselenophene is an organochalcogen compound with the chemical formula C4H3ClSe. It is a derivative of selenophene, a heterocyclic aromatic compound containing selenium, with one hydrogen atom replaced by a chlorine atom. This halogenated compound exhibits a planar structure due to its aromatic nature, with the chlorine atom attached to one of the carbon atoms in the ring. 2-Chloroselenophene is an important intermediate in the synthesis of various organoselenium compounds, which have applications in pharmaceuticals, agrochemicals, and materials science. It is typically synthesized through the reaction of 2-lithioselenophene with chlorotrimethylsilane or through the electrophilic chlorination of selenophene. Due to its reactivity, 2-chloroselenophene can undergo various chemical transformations, such as nucleophilic substitution, addition reactions, and coupling reactions, making it a valuable building block in organic synthesis.

Check Digit Verification of cas no

The CAS Registry Mumber 1449-67-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,4 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1449-67:
(6*1)+(5*4)+(4*4)+(3*9)+(2*6)+(1*7)=88
88 % 10 = 8
So 1449-67-8 is a valid CAS Registry Number.
