Check Digit Verification of cas no

The CAS Registry Mumber 98405-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,4,0 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98405-65:
(7*9)+(6*8)+(5*4)+(4*0)+(3*5)+(2*6)+(1*5)=163
163 % 10 = 3
So 98405-65-3 is a valid CAS Registry Number.

SYNTHESIS OF CYCLOHEPTA-1,3,5-TRIENES BY THE REACTION OF AROMATIC HYDROCARBONS WITH DIAZO COMPOUNDS IN THE PRESENCE OF TRANSITION METAL COMPLEXES

Dzhemilev, U. M.,Dokichev, V. A.,Sultanov, S. Z.,Sadykov, R. A.,Tolstikov, G. A.,Nefedov, O. M.

, p. 945 - 950 (2007/10/02)

A preparative method has been developed for the synthesis of cyclohepta-1,3,5-trienes, using a reaction of aromatic hydrocarbons with diazomethane, methyldiazoacetate, adamantanoyldiazomethane, and 1-diazo-3-phenylpropan-2-one, with rhodium trifluoroacetate as catalyst.The order of activity and the relative reactivity coefficients of substituted benzenes have been determined, and the link between these characteristics and the energy of the highest occupied molecular orbital of the aromatic ring has been established.In catalyzed reactions of benzenes with diazomethaneor methyldiazoacetate, leading to cycloheptatrienes, effects of chemical polarization of the ring have not been observed.
