Thiophenium, 1-methyl-, also known as 1-methylthiophenium, is a chemical compound with the molecular formula C5H7S. It is a heterocyclic compound consisting of a thiophene ring with a methyl group attached to the 1-position. Thiophene is a five-membered aromatic ring containing one sulfur atom, and the addition of a methyl group at the 1-position modifies its chemical properties. Thiophenium, 1-methyl- is an important intermediate in the synthesis of various organic compounds, particularly those containing thiophene rings, which are found in pharmaceuticals, agrochemicals, and materials science. Due to its reactivity and potential applications, 1-methylthiophenium is a subject of interest in organic chemistry research.

3331-14-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 3331-14-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,3,3 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.Calculate Digit Verification of CAS Registry Number 3331-14:
(6*3)+(5*3)+(4*3)+(3*1)+(2*1)+(1*4)=54
54 % 10 = 4
So 3331-14-4 is a valid CAS Registry Number.
