Check Digit Verification of cas no
The CAS Registry Mumber 13289-90-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,2,8 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13289-90:
(7*1)+(6*3)+(5*2)+(4*8)+(3*9)+(2*9)+(1*0)=112
112 % 10 = 2
So 13289-90-2 is a valid CAS Registry Number.

Furan Derivatives. Part 9. Synthesis and Properties of Cycloheptabenzofurans
Horaguchi, Takaaki,Tanemura, Kiyoshi,Suzuki, Tsuneo
, p. 39 - 43 (2007/10/02)
Cycloheptabenzofurans 1a-c were synthesized by heating (5-oxo-5H-benzocyclohepten-4-yloxy)acetic acids 7a-c with sodium acetate in acetic anhydride or by irradiation of 7a-c in acetonitrile.Several reactions such as protonation, catalytic hydrogenation, Diels-Alder reaction, acylation, and photoreaction were examined for 1a-b.The results show that cycloheptabenzofurans have both properties of heptafulvene and benzofuran.The carbon-carbon double bond in the furan ring of 1a has aromatic character, however, the carbon-carbon double bonds in the seven-membered ring have olefinic character.
