Check Digit Verification of cas no

The CAS Registry Mumber 780777-83-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,0,7,7 and 7 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 780777-83:
(8*7)+(7*8)+(6*0)+(5*7)+(4*7)+(3*7)+(2*8)+(1*3)=215
215 % 10 = 5
So 780777-83-5 is a valid CAS Registry Number.

Synthesis of derivatives of the new condensed system 4H,7H-furo[3′, 4′:6,7]cyclohepta[1,2-b]pyran

Arsen'eva,Arsen'ev

experimental part, p. 136 - 142 (2009/04/03)

8-Hydroxy-1,3-dimethyl-4H-cyclohepta[c]furan-4-one reacts with arylidenemalononitriles and, like 1,3-oxo enols, forms the corresponding condensed 2-amino-4H-pyrans. The analogous reaction with 3-(dicyanomethylene) indolin-2-ones give spirocyclic 2-amino-4
