Check Digit Verification of cas no

The CAS Registry Mumber 90238-20-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,2,3 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90238-20:
(7*9)+(6*0)+(5*2)+(4*3)+(3*8)+(2*2)+(1*0)=113
113 % 10 = 3
So 90238-20-3 is a valid CAS Registry Number.

Photochemical Reactions of Substituted Benzenes with Aliphatic Amines

Gilbert, Andrew,Krestonosich, Stefan,Westover, David L.

, p. 295 - 302 (2007/10/02)

The products arising from the irradiation of diethylamine and t-butylamine with toluene, chlorobenzene, anisole, benzonitrile, benzyl fluoride, benzotrifluoride (α,α,α-trifluorotoluene), m-fluorobenzotrifluoride (α,α,α,m-tetrafluorotoluene), p-fluorotoluene, m-fluorotoluene, p-fluoroanisole, m-fluoroanisole, and 1,3-bis(trifluoromethyl)benzene, and of triethylamine with toluene, benzotrifluoride and 1,3-bis(trifluoromethyl)benzene, all at 254 nm, are described.Reaction pathways involving both substitution and 1,2- and 1,4-acyclic addition processes are observed and which predominates depends upon the arene substituent.The novel acyclic adduct, Me2C=CH-CH=CH-CH=NBut, is obtained from toluene and t-butylamine and, contrary to previous reports, chlorobenzene yields arene-amine 1:1 adducts as well as the amine α-substitution product (16); benzonitrile gives aniline derivatives with the primary and secondary amines.
