Check Digit Verification of cas no

The CAS Registry Mumber 74694-99-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,9 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74694-99:
(7*7)+(6*4)+(5*6)+(4*9)+(3*4)+(2*9)+(1*9)=178
178 % 10 = 8
So 74694-99-8 is a valid CAS Registry Number.

The Thermal Elimination of Iodine from Some Substituted α-Iodonaphthalenes: a Structural Study

Cameron, Donald W.,Feutrill, Geoffrey I.,Pannan, Linda J. H.,Raston, Colin L.,Skelton, Brian W.,White, Allan H.

, p. 610 - 627 (2007/10/02)

Brief heating of a number of methyl 8-iodo-5,7-dimethoxy-2-naphthoate derivatives with a variety of added hydroxy-, methoxy-, or acetoxy-substituents in the 4- and 6-positions has been found to result in facile elimination of iodine in certain compounds but not others; subsequent examination of other aspects of the chemistry of the system have suggested this to be a solid state effect.Single crystal X-ray structure determinations have been carried out on a representative selection of compounds, suggesting that in those examples where elimination has been found to occur, intimate charge-transfers interactions between the conjugated systems of adjacent molecules arising from the nature of the crystal packing are responsible; in those compounds which do not eliminate iodine, similar interactions may also be found but are associated with substituent out-of-plane steric interactions which hinder relative movement of the naphthalene moieties in the lattice.

Synthesis of a Natural Hexachloro Dinaphthofuran Quinone

Cameron, Donald W.,Feutrill, Geoffrey I.,Pannan, Linda J. H.

, p. 2531 - 2541 (2007/10/02)

1,3,6,8,11,13-Hexachloro-4,10-dihydroxy-5,9-dihydrodinaphthofuran-5,9-dione (1), a pigment isolated from soils and the only natural example of this ring system, has been synthesized for the first time.
