Check Digit Verification of cas no

The CAS Registry Mumber 92892-09-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,8,9 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 92892-09:
(7*9)+(6*2)+(5*8)+(4*9)+(3*2)+(2*0)+(1*9)=166
166 % 10 = 6
So 92892-09-6 is a valid CAS Registry Number.

THE KINETICS OF THE REACTIONS OF 2,6-DI-t-BUTYL-4-METHYLPHENOL AND 2,4,6-TRIMETHYLPHENOL WITH NITROGEN DIOXIDE IN SOLUTION

Coombes, Robert G.,Diggle, Andrew W.,Kempsell, Stewart P.

, p. 2037 - 2040 (2007/10/02)

The reaction of 2,6-di-t-butyl-4-methylphenol with nitrogen dioxide to form 2,6-di-t-butyl-4-methyl-4-nitrocyclohexa-2,5-dienone has a first order dependence of rate on the concentration of the species N2O4.By contrast the observed rate of the correspondi

ipso-Attack in the Nitration of Aromatic Amines. Part 2. Isolation of Salts and Other Products resulting from ipso-Attack

Helsby, Paul,Ridd, John H.

, p. 311 - 316 (2007/10/02)

In 70percent nitric acid at 0 deg C, NN,2,4,6-pentamethylaniline undergoes ipso-attack at the 4-position to form the relatively stable ipso-intermediate (2); this ion can be precipitated as the hexafluorophosphate.In more aqueous media, the dimethylamino group is displaced by water to form the hexadienone (4).In aqueous nitric acid at 0 deg C, NN,2,4-tetramethyl-6-nitroaniline undergoes both ipso-attack and addition of water to the ring to form the adduct (8); this ion can also be precipitated as the hexafluorophosphate.The reaction of NN,2,6-tetramethyl-4-methoxyaniline with 52 percent nitric acid at 0 deg C also involves displacement of the dimethylamino group and gives finally 2,6-dimethylbenzoquinone.The initial stages of the reactions of the above amines require the presence of nitrous acid and the reactions are inhibited by hydrazine.
