Check Digit Verification of cas no
The CAS Registry Mumber 406-41-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,0 and 6 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 406-41:
(5*4)+(4*0)+(3*6)+(2*4)+(1*1)=47
47 % 10 = 7
So 406-41-7 is a valid CAS Registry Number.

Method for producing 4,4,4- Trifluorobutane-2-One
-
Page/Page column 6-7, (2009/09/26)
The present invention provides a novel method for preparing 4,4,4-trifluorobutane-2-one by providing a fluorobutene selected from the group consisting of 2,4,4,4-tetrafluoro-1-butene, (E)-1,1,1,3-tetrafluoro-2-butene, (Z)-1,1,1,3-tetrafluoro-2-butene, and mixture thereof; and reacting the fluorobutene(s) with a proton acid and water.
