Check Digit Verification of cas no

The CAS Registry Mumber 37592-88-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,7,5,9 and 2 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 37592-88:
(7*3)+(6*7)+(5*5)+(4*9)+(3*2)+(2*8)+(1*8)=154
154 % 10 = 4
So 37592-88-4 is a valid CAS Registry Number.

Organocatalytic oxidation of substituted anilines to azoxybenzenes and nitro compounds: Mechanistic studies excluding the involvement of a dioxirane intermediate

Voutyritsa, Errika,Theodorou, Alexis,Kokotou, Maroula G.,Kokotos, Christoforos G.

supporting information, p. 1291 - 1298 (2017/06/06)

An organocatalytic and environmentally friendly approach for the selective oxidation of substituted anilines was developed. Utilizing a 2,2,2-trifluoroacetophenone-mediated oxidation process, substituted anilines can be transformed into azoxybenzenes, while a simple treatment with MeCN and H2O2 leads to the corresponding nitro compounds, providing user-friendly protocols that can be easily scaled up. Various substitution patterns and functional groups were tolerated leading to products in high to excellent yields. Mechanistic studies utilizing HRMS provide clear evidence for the distinct mechanistic intermediates that are involved. This study constitutes an indirect proof excluding the involvement of a dioxirane intermediate in the green organocatalytic oxidation, utilizing 2,2,2-trifluoroacetophenone as the catalyst.

Process for preparing 2,3-dihydro-1,3-dialkyl-2,3-dialkyl perimidines and N,N-'-dialkyl-1,8-naphthalene diamines

-

, (2008/06/13)

Processes for preparing 2,3-dihydro-1,3-dialkyl-2,2-dialkyl perimidines and N,N'-dialkyl-1,8-naphthalene diamines are disclosed. The 2,3-dihydro-1,3-dialkyl-2,2-dialkyl perimidines are prepared by alkylating 2,3-dihydro-2,2-dialkyl perimidines with an alkylating agent in a water miscible organic solvent at room temperature to 80° C. in the presence of water and an inorganic base. N,N'-dialkyl-1,8-naphthalene diamines are prepared by hydrolyzing the 2,3-dihydro-1,3-dialkyl-2,2-dialkyl perimidines with strong aqueous acid in an aqueous organic solvent and removing a ketone by-product and the aqueous organic solvent by codistillation.
