Check Digit Verification of cas no

The CAS Registry Mumber 30653-80-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,6,5 and 3 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 30653-80:
(7*3)+(6*0)+(5*6)+(4*5)+(3*3)+(2*8)+(1*0)=96
96 % 10 = 6
So 30653-80-6 is a valid CAS Registry Number.

Syntheses with Nitriles, LXXXIII: On Dicyanomethylene-aminoindenes, Indano-pyridazines and Indano-pyridines

Junek, Hans,Klade, Manfred,Sterk, Heinz

, p. 781 - 788 (1989)

1-Dicyanomethylene-3-indanone (1) shows a remarkable reactivity of the carbonyl- and the methylene-function towards nucleophiles.With anilines and phenylhydrazine, resp., the deep-red colored pentamethinecyanines 2 and 3 are formed, azocoupling leads to indano-pyridazines 4.With diphenylformamidines anilinomethylene-indanones 5 are obtained in a primary reaction, followed by ring closure and Dimroth-rearrangement to indano-pyridines 6. 13C- and 15N-NMR-spectroscopy is used for confirmation of the structures. - Keywords: 1-Dicyanomethylene-3-indanone; 1-Dicyanomethylene-3-phenylamino-2-indenes; Indano-(2,1-c)pyridazines; Phenylamino-indano-(2,1-c)pyridines.
