6937-04-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6937-04-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,9,3 and 7 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 6937-04:
(6*6)+(5*9)+(4*3)+(3*7)+(2*0)+(1*4)=118
118 % 10 = 8
So 6937-04-8 is a valid CAS Registry Number.

CONTRASTING REACTIONS OF 2,6-DICHLORO-4-TRICHLOROMETHYLPYRIDINE, 2,6-DICHLORO-3-TRICHLOROMETHYLPYRIDINE AND THEIR N-OXIDES WITH NUCLEOPHILES

Dainter, Ronald S.,Suschitzky, Hans,Wakefield, Basil J.

, p. 227 - 234 (2007/10/02)

Various nucleophiles react with 2,6-dichloro-4-trichloromethylpyridine and 2-chloro-6-trichloromethylpyridine as expected, by displacement of ring chlorine atoms.But in the reactions of nucleophiles with 2,6-dichloro-3-trichloromethylpyridine and 2,6-difluoro-3-trifluoromethylpyridine, displacement of ring halogen atoms is accompained or followed by multiple attack at the trihalogenomethyl group.The reactivity of the trihalogenomethyl groups is modified by N-oxidation.A mechanism for the peculiar reactivity of the trihalogenomethyl groups is proposed, involving loss of halide ion from the CX3 group assisted by Ione pairs on substituents or negative charge in Meisenheimer intermediates.Both geometrical isomers of 1,2-dichloro-1,2-bis(2,6-dichloro-3-pyridyl)ethene are described.
