Check Digit Verification of cas no

The CAS Registry Mumber 619-97-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,1 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 619-97:
(5*6)+(4*1)+(3*9)+(2*9)+(1*7)=86
86 % 10 = 6
So 619-97-6 is a valid CAS Registry Number.

Nitrosation of Aniline by N2O4

Aziz, A.,Hoharum, M.,Khalil, Mutasim I.

, p. 1737 - 1742 (1981)

Kinetics of nitrosation of aniline by N2O4 in donor non-aqueous solvents, e.g. acetonitrile, ethylacetate and a 1:1 v/v mixture of both, have been studied.The reaction is first-order with respect to N2O4 and zero-order with respect to aniline in each of the donor solvents added.The average observed order of k values is ethylacetate (7.195xE-3) > acetonitrile (4.773xE-3) > 1.1 v/v acetonitrile + ethylacetate mixture (3.216xE-3S-1).The variation of k values in the different solvents is interpreted in terms of solvation ability of the solvents.Conductivity measurements and u.v. studies of N2O4 solutions are reported.Both the initial and integral rate methods show that rate-determining step is the one which involves the formation of the nitrosating agent, NO+, from N2O4.Accordingly a mechanism of nitrosation is proposed.
