Check Digit Verification of cas no
The CAS Registry Mumber 79623-37-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,6,2 and 3 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 79623-37:
(7*7)+(6*9)+(5*6)+(4*2)+(3*3)+(2*3)+(1*7)=163
163 % 10 = 3
So 79623-37-3 is a valid CAS Registry Number.

Alcoholysis of trifluoromethyl groups attached to the pyridine ring
Qian, Xuhong,Liu, Shuyou
, p. 9 - 12 (2007/10/03)
In dimethylformamide solution, trifluoroethoxylation and methoxylation of 5-chloro-3-trifluoromethylpyridine (2) yield 5-chloro-3-tris(trifluoroethoxyl)methyl pyridine (2a) and a dimethyl ketal of 3-chloronicotinic acid anhydride (2b) with fluorines as leaving groups, respectively. The corresponding reactions of 2,3-dichloro-5-trifluoromethylpyridine (3) only yield the 2-alkoxy-substituted products 3a and 3b with chloro as the leaving group and the 2-dimethylamino product 3c which was formed by the action of solvent dimethylformamide as a nucleophile. Differences in their reaction behaviour and possible mechanisms are also discussed.
