Check Digit Verification of cas no

The CAS Registry Mumber 77989-06-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,8 and 9 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 77989-06:
(7*7)+(6*7)+(5*9)+(4*8)+(3*9)+(2*0)+(1*6)=201
201 % 10 = 1
So 77989-06-1 is a valid CAS Registry Number.

Derivatives of 2H-Indenoisoquinoline

Neidlein, Richard,Gartner, Rolf

, p. 61 - 65 (2007/10/02)

The synthesis of the derivatives 1a-1i of 1,3,6,7-tetrahydro-2H-indenoisoquinoline-1,3-dione is reported.It was impossible to oxidize these compounds to the 1,3-dihydro derivatives 2a-2i.The carbocyclic analogue, 7-methoxy-5H-cyclopentaphenalen-5-one (5), reacts with 2,4-dinitrophenylhydrazine to yield the hydrazone 6.
