94691-80-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94691-80-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,6,9 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 94691-80:
(7*9)+(6*4)+(5*6)+(4*9)+(3*1)+(2*8)+(1*0)=172
172 % 10 = 2
So 94691-80-2 is a valid CAS Registry Number.

NEW CONDENSED TRI- AND TETRACYCLIC PYRAZOLE RING SYSTEMS
Svetlik, Jan
, p. 2513 - 2516 (2007/10/02)
1-Phenylpyrrazolopyrrolopyrazine and its 5-aza analogue were synthesized from ethyl 5-amino-1-phenylpyrazole-4-carboxylate.Additional azolo ring annelations on the pyrazine part of the first heterocycle afforded new tetracyclic systems with two common nitrogen atoms.
