The chemical compound "4,4'-dimethyl-4,4'-(2,5-dimethyl-1,1-dioxo-2,5-dihydro-1H-1λ6-[1,3,4]thiadiazole-2,5-diyl)-bis-cyclohexanone" is a complex organic molecule with a molecular formula of C20H26N2O4S2. It features a cyclohexanone core with two methyl groups at the 4,4' positions, and a 1,3,4-thiadiazole ring system connecting the two cyclohexanone units. The thiadiazole ring is itself substituted with two methyl groups at the 2,5 positions and contains a 1,1-dioxo group, indicating the presence of two carbonyl groups. 4,4'-dimethyl-4,4'-(2,5-dimethyl-1,1-dioxo-2,5-dihydro-1H-1λ6-[1,3,4]thiadiazole-2,5-diyl)-bis-cyclohexanone is characterized by its unique structure, which may have specific applications in chemical research or industrial processes, although the exact uses are not specified in the provided information.
The CAS Registry Mumber 7105-81-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,0 and 5 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 7105-81: (6*7)+(5*1)+(4*0)+(3*5)+(2*8)+(1*1)=79 79 % 10 = 9 So 7105-81-9 is a valid CAS Registry Number.
