2-(2,4-dinitro-phenylsulfanyl)-5-(2-ethoxy-phenyl)-[1,3,4]oxadiazole is a complex organic compound with the molecular formula C14H10N4O6S. It features a 1,3,4-oxadiazole ring, which is a five-membered heterocyclic ring containing two nitrogen atoms and one oxygen atom. The compound has a 2,4-dinitrophenylsulfanyl group attached to the 2-position of the oxadiazole ring, which consists of a 2,4-dinitrophenyl group (a benzene ring with two nitro groups at the 2 and 4 positions) connected to a sulfanyl group (a sulfur atom with two hydrogen atoms). Additionally, a 2-ethoxyphenyl group is attached to the 5-position of the oxadiazole ring, which is a benzene ring with an ethoxy group (an ethoxy group is an ethyl group attached to an oxygen atom) at the 2 position. This chemical is known for its potential applications in various fields, such as pharmaceuticals and materials science, due to its unique structure and properties.
The CAS Registry Mumber 19982-36-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,8 and 2 respectively; the second part has 2 digits, 3 and 6 respectively. Calculate Digit Verification of CAS Registry Number 19982-36: (7*1)+(6*9)+(5*9)+(4*8)+(3*2)+(2*3)+(1*6)=156 156 % 10 = 6 So 19982-36-6 is a valid CAS Registry Number.
