21146-81-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21146-81-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,4 and 6 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 21146-81:
(7*2)+(6*1)+(5*1)+(4*4)+(3*6)+(2*8)+(1*1)=76
76 % 10 = 6
So 21146-81-6 is a valid CAS Registry Number.

Thioether substituted hydroxybenzophenones and stabilized compositions
-
, (2008/06/13)
2-Hydroxybenzophenone derivatives substituted in the 4′-position by a thioether moiety exhibit enhanced absorption in the UV at longer wavelength. Compositions comprising organic material subject to actinic degradation are beneficially stabilized with such derivatives.
