The chemical compound "N'-(5,5-dimethyl-5H-[1,3,4]thiadiazol-2-ylidene)-N,N-dimethyl-benzene-1,4-diamine" is a complex organic molecule with a unique structure. It features a benzene-1,4-diamine core, which is a derivative of benzene with two amino groups attached to the 1 and 4 positions. The molecule is further characterized by the presence of a 5,5-dimethyl-5H-[1,3,4]thiadiazol-2-ylidene group, which is a heterocyclic ring system with a sulfur atom and two nitrogen atoms. This group is connected to the benzene-1,4-diamine through a methylene bridge, and both amino groups are N,N-dimethylated, meaning they have two methyl groups attached to each nitrogen. N'-(5,5-dimethyl-5H-[1,3,4]thiadiazol-2-ylidene)-N,N-dimethyl-benzene-1,4-diamine is known for its potential applications in various chemical and pharmaceutical processes, particularly as a building block for the synthesis of more complex molecules.
The CAS Registry Mumber 25688-09-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,6,8 and 8 respectively; the second part has 2 digits, 0 and 9 respectively. Calculate Digit Verification of CAS Registry Number 25688-09: (7*2)+(6*5)+(5*6)+(4*8)+(3*8)+(2*0)+(1*9)=139 139 % 10 = 9 So 25688-09-9 is a valid CAS Registry Number.
