63941-39-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 63941-39-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,9,4 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 63941-39:
(7*6)+(6*3)+(5*9)+(4*4)+(3*1)+(2*3)+(1*9)=139
139 % 10 = 9
So 63941-39-9 is a valid CAS Registry Number.

Hydroxybenzylmalonic acid derivatives
-
, (2008/06/13)
Hydroxybenzylmalonic acid derivatives of 1-acylpiperidin-4-ols or 1-acyl-4-aminopiperidines respectively having the formula STR1 WHEREIN Ra, Rb, Rc, Rd are hydrocarbon residues, Re is H or lower alkyl, R1 is a hydroxybenzyl residue, R2 is H or R1, X is --O-- or --NH-- and Y is hydrogen, a hydrocarbon, amino, alkoxy or phenoxy residue are excellent stabilizers for plastics material, especially for polyolefins. They act against heat aging as well as against light aging. The compounds may be prepared by acylation of the corresponding NH compounds or by hydroxybenzylation of the corresponding malonic acid derivatives.
