[1,2,4]Triazolo[1,5-a]pyrimidine-6-carbonitrile, 7-chloro-5-[(4-chlorophenyl)amino]- is a complex organic compound with the molecular formula C11H5Cl2N5. It features a triazolo[1,5-a]pyrimidine core, which is a fused ring system consisting of a triazole and a pyrimidine. The compound has a 7-chloro substituent, which is a chlorine atom attached to the 7th carbon of the triazolo[1,5-a]pyrimidine ring, and a 5-[(4-chlorophenyl)amino] group, indicating an amino group attached to a 4-chlorophenyl group at the 5th position. This molecule is characterized by its two chlorine atoms, one on the phenyl ring and another on the triazolo[1,5-a]pyrimidine core, contributing to its overall structure and potential reactivity.
The CAS Registry Mumber 98190-44-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,1,9 and 0 respectively; the second part has 2 digits, 4 and 4 respectively. Calculate Digit Verification of CAS Registry Number 98190-44: (7*9)+(6*8)+(5*1)+(4*9)+(3*0)+(2*4)+(1*4)=164 164 % 10 = 4 So 98190-44-4 is a valid CAS Registry Number.
