3639-22-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3639-22-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,6,3 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 3639-22:
(6*3)+(5*6)+(4*3)+(3*9)+(2*2)+(1*2)=93
93 % 10 = 3
So 3639-22-3 is a valid CAS Registry Number.

Process for the preparation of E-2-propyl-2-pentenoic acid and physiologically compatible salts thereof

-

, (2008/06/13)

A novel process for the preparation of E-2-propyl-2-pentenoic acid and its physiologically compatible salts is described, in which di-n-propyl-ketone-cyanohydrin is used as the starting compound. The compound is either (a) dehydrated with thionyl chloride and the acid nitrile formed is subsequently saponified with a stoichiometric excess of potassium hydroxide, or (b) is initially converted into 2-hydroxy-2-propyl-pentanoic acid and the latter is subsequently dehydrated in the presence of a less than stoichiometric quantity of a tertiary amine at a temperature of at least 200° C. The free acid is optionally converted into the salt form, preferably using the corresponding salts of carbon dioxide in an aqueous acetone solution.
