2-Selenophthalide is an organic compound with the chemical formula C8H4Se. It is a derivative of phthalide, where one of the oxygen atoms in the phthalide ring is replaced by a selenium atom. This substitution results in a heterocyclic compound that exhibits unique chemical properties due to the presence of selenium. 2-Selenophthalide is of interest in organic chemistry and materials science, particularly for its potential applications in the synthesis of various selenophene-containing compounds and as a precursor in the preparation of other organoselenium compounds. Its structure and reactivity make it a valuable building block in the development of new materials and pharmaceuticals.

Check Digit Verification of cas no

The CAS Registry Mumber 4938-13-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,9,3 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 4938-13:
(6*4)+(5*9)+(4*3)+(3*8)+(2*1)+(1*3)=110
110 % 10 = 0
So 4938-13-0 is a valid CAS Registry Number.
