5,5-dimethyl-4-(phenylsulfanyl)furan-2(5H)-one is a chemical compound characterized by a furan-2(5H)-one core structure, which features a five-membered ring with a carbonyl group at position 2. The molecule is further defined by two methyl groups (CH3) at the 5,5-positions, which are symmetrically located on the ring, and a phenylsulfanyl group (C6H5-S-) attached at the 4-position. This phenylsulfanyl group consists of a benzene ring (C6H5) linked to a sulfur atom, which in turn is connected to the furan ring. The compound is an example of a heterocyclic compound, with sulfur being the heteroatom in the phenylsulfanyl group. It is likely to have specific chemical properties due to the presence of the sulfur atom and the aromatic ring, which may influence its reactivity, stability, and potential applications in various chemical or pharmaceutical contexts.

77199-32-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 77199-32-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,1,9 and 9 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 77199-32:
(7*7)+(6*7)+(5*1)+(4*9)+(3*9)+(2*3)+(1*2)=167
167 % 10 = 7
So 77199-32-7 is a valid CAS Registry Number.
