Check Digit Verification of cas no

The CAS Registry Mumber 304678-70-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,4,6,7 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 304678-70:
(8*3)+(7*0)+(6*4)+(5*6)+(4*7)+(3*8)+(2*7)+(1*0)=144
144 % 10 = 4
So 304678-70-4 is a valid CAS Registry Number.

Dipyrrolo[1,2-a:1',2'-c]quinazoline, a new ring system of biological interest

Mingoia, Francesco,Diana, Patrizia,Barraja, Paola,Lauria, Antonino,Almerico, Anna Maria

, p. 1975 - 1985 (2007/10/03)

Dipyrrolo[1,2-a:1',2'-c]quinazoline derivatives (10a-c) and (11b,c) were obtained in moderate to good yields by trifluoromethanesulfonic acid catalyzed decomposition of 2-(3-azidophenyl)- 1-(1H-pyrrol-2-yl)pyrroles (8a-c), through cyclisation of the protosolvated intermediates arylnitrenium ions (9).
