Pyrazino[1,2-a]indole is a heterocyclic compound characterized by a pyrazine ring fused to an indole nucleus. This unique structure is formed by the fusion of a pyrazine ring (a six-membered ring with two nitrogen atoms) to the 1 and 2 positions of an indole ring (a bicyclic structure consisting of a benzene ring fused to a pyrrole ring). Pyrazino[1,2-a]indole is an important scaffold in medicinal chemistry and has been found in various bioactive compounds with potential applications in the development of new drugs, particularly in the treatment of neurological disorders and cancer. Its chemical properties and reactivity make it a valuable target for synthetic chemists, who explore its derivatives and potential applications in pharmaceutical research.
The CAS Registry Mumber 245-44-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,4 and 5 respectively; the second part has 2 digits, 4 and 4 respectively. Calculate Digit Verification of CAS Registry Number 245-44: (5*2)+(4*4)+(3*5)+(2*4)+(1*4)=53 53 % 10 = 3 So 245-44-3 is a valid CAS Registry Number.
