4-amino-2-chloro-5,6,7,8-tetrahydroquinazoline is a heterocyclic organic compound with the molecular formula C9H11ClN4. It is a derivative of quinazoline, a fused bicyclic system consisting of a benzene ring and a pyrazine ring. The compound features a chloro group at the 2-position, an amino group at the 4-position, and a tetrahydro ring structure, which means that the molecule has undergone hydrogenation, reducing the double bonds in the original quinazoline ring system. 4-amino-2-chloro-5,6,7,8-tetrahydroquinazoline is of interest in medicinal chemistry due to its potential as a building block for the synthesis of various pharmaceuticals, particularly those with antiviral and anticancer properties. Its chemical structure allows for further functionalization and modification, making it a versatile intermediate in the development of new drugs.
The CAS Registry Mumber 1127-86-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,2 and 7 respectively; the second part has 2 digits, 8 and 6 respectively. Calculate Digit Verification of CAS Registry Number 1127-86: (6*1)+(5*1)+(4*2)+(3*7)+(2*8)+(1*6)=62 62 % 10 = 2 So 1127-86-2 is a valid CAS Registry Number.
