14090-47-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 14090-47-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,0,9 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14090-47:
(7*1)+(6*4)+(5*0)+(4*9)+(3*0)+(2*4)+(1*7)=82
82 % 10 = 2
So 14090-47-2 is a valid CAS Registry Number.

The 2- or 6-(α-Hydroxyalkyl- and α-Oxoalkyl)-5,8-dimethoxy-1,4-naphtoquinones from the Oxidative Demethylation of 2-(α-Hydroxyalkyl- and α-Oxoalkyl)-1,4,5,8-tetramethoxynaphthalenes with Cerium(IV) Ammonium Nitrate, and the Further Demethylations to Naphthazarins

Tanoue, Yasuhiro,Terada, Akira

, p. 2039 - 2046 (1988)

Oxidative demethylation of 2-(α-hydroxyalkyl- and α-oxoalkyl)-1,4,5,8-tetramethoxynaphthalene with (NH4)2Ce(NO3)6 gave two isomeric dimethoxynaphthoquinones: 2-substituted and 6-substituted 5,8-dimethoxy-1,4-naphthoquinones.Further demethylations of the former isomer to the corresponding dihydroxynaphthoquinones required an AgO-40percentHNO3 reagent, while the latter isomers needed AlCl3 as the demethylation reagent.Some comments regarding the mechanism of these oxidative demethylations with (NH4)2Ce(NO3)6 are given.
