Check Digit Verification of cas no
The CAS Registry Mumber 431-05-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,3 and 1 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 431-05:
(5*4)+(4*3)+(3*1)+(2*0)+(1*5)=40
40 % 10 = 0
So 431-05-0 is a valid CAS Registry Number.

Process for producing 1,1,1-trifluoroacetone
-
Example 4,6, (2008/06/13)
A process for producing 1,1,1-trifluoroacetone includes the step of conducting a hydrogenolysis of a halogenated trifluoroacetone, which is represented by the general formula (1), by a hydrogen gas in the presence of a catalyst containing a transition metal, where X represents a chlorine, bromine or iodine, and n represents an integer from 1 to 3. It is possible to obtain 1,1,1-trifluoroacetone with a high yield by using the special catalyst.
