Check Digit Verification of cas no
The CAS Registry Mumber 2390-59-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,9 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2390-59:
(6*2)+(5*3)+(4*9)+(3*0)+(2*5)+(1*9)=82
82 % 10 = 2
So 2390-59-2 is a valid CAS Registry Number.

Method for preparing triarylmethane compounds and application thereof
-
Paragraph 0034-0036, (2019/11/13)
The invention discloses a method for preparing a triarylmethane dye. 4,4'-N,N-disubstituted aminodiphenylmethane (bass) and aromatic amines or substituted aromatic amines, phenols or substituted phenols are dissolved in a solvent, metal complexes and tetrachlorobenzoquinone are used as catalysts and oxygen is used as oxidant, the mixture reacts for 5-8 hours at acid conditions and a certain temperature, so that the product triarylmethane dye is obtained in one step, and the commercialized product is obtained through further treatment, so as to meet the application requirement in different fields. The method is simple and safe, and has high yield and less three-wastes.
Carbenium ion-carbinol equilibration for basic triarylmethane dyes: Relative reactivities of dyes in aq. solutions
Gupta, Susanta K. Sen,Arvind, Udai
, p. 998 - 1000 (2007/10/02)
Equilibria and kinetics of carbenium ion-to-carbinol base reactions for a set of selected basic triarylmethane dyes in aq. buffer solutions of low ionic strength have been measured spectrophotometrically.Relative reactivities of the dyes towards nucleophilic attack by hydroxide ion, on the basis of both equilibrium constant and forward rate constant of the reaction, have been found to follow the same order: malachite green (MG)> brillant green (BG)>> Victoria pure blue BO(VB)> methyl violet (MV) = crystal violet (CV)> ethyl vioet (EV).A fairly good correlation between elec trophilicities of the dyes and ?R+ parameters of their 4-alkylamino substituents has been obtained
