3-methyl-5,6-dihydro-4H-cyclopenta[b]thiophen-4-one is a heterocyclic organic compound characterized by a five-membered ring structure with a sulfur atom and a carbonyl group. It features a methyl group attached to the third carbon and a double bond between the fourth and fifth carbons, which is part of a dihydro (partially hydrogenated) system. 3-methyl-5,6-dihydro-4H-cyclopenta[b]thiophen-4-one is a derivative of cyclopenta[b]thiophene, a type of thiophene that has a cyclopentane ring fused to it. The presence of the carbonyl group at the 4-position gives it a ketone functionality, which can participate in various chemical reactions. 3-methyl-5,6-dihydro-4H-cyclopenta[b]thiophen-4-one may be of interest in organic synthesis and could potentially have applications in the development of pharmaceuticals or other chemical products due to its unique structure and reactivity.

5833-99-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 5833-99-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,8,3 and 3 respectively; the second part has 2 digits, 9 and 9 respectively.Calculate Digit Verification of CAS Registry Number 5833-99:
(6*5)+(5*8)+(4*3)+(3*3)+(2*9)+(1*9)=118
118 % 10 = 8
So 5833-99-8 is a valid CAS Registry Number.
