39252-31-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 39252-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,9,2,5 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 39252-31:
(7*3)+(6*9)+(5*2)+(4*5)+(3*2)+(2*3)+(1*1)=118
118 % 10 = 8
So 39252-31-8 is a valid CAS Registry Number.

Novel bis(3',5'-mono or dihydrocarbyl-4'-hydroxybenzyl)-1,3-diketones are prepared by reacting a (3',5'-mono or dihydrocarbyl-4'-hydroxybenzyl)-1,3-diketone with an N,N-dihydrocarbyl-2,6-mono or dihydrocarbyl-4-aminomethylphenol and an alkyl halide in the presence of an alkaline earth metal halide. The products are useful as antioxidants.
