Check Digit Verification of cas no
The CAS Registry Mumber 313-80-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,1 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 313-80:
(5*3)+(4*1)+(3*3)+(2*8)+(1*0)=44
44 % 10 = 4
So 313-80-4 is a valid CAS Registry Number.

Synthesis of 1-Azapyrene
Tanga, Mary J.,Reist, Elmer J.
, p. 747 - 752 (2007/10/02)
The environmental contaminants 1-azapyrene 15, 2-azapyrene 13 and several other azapyrene derivatives were synthesized from a common intermediate, 2,2a,3,4-tetrahydrocyclopentaphenalen-1-one oxime 6.The synthesis of 1-azapyrene 15 completes the series of azapyrenes.
