Check Digit Verification of cas no
The CAS Registry Mumber 40649-56-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,6,4 and 9 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 40649-56:
(7*4)+(6*0)+(5*6)+(4*4)+(3*9)+(2*5)+(1*6)=117
117 % 10 = 7
So 40649-56-7 is a valid CAS Registry Number.

Process for production of 3-hydroxy-cyclohexene-2-ones
-
, (2008/06/13)
Substituted cyclohexene-2-ones are prepared by reacting a cyanoethylated ketone, such as 1,1,1-tri-beta-cyanoethyl acetone, in a polar solvent, e.g., methanol or water, in the presence of a catalyst. The compounds formed are useful in the production of cyclic amino acids, esters, hydroxy acids, as modifiers and as hardeners for phenolic and epoxide resins and as additives for lubricating oils.
