172154-79-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172154-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,1,5 and 4 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 172154-79:
(8*1)+(7*7)+(6*2)+(5*1)+(4*5)+(3*4)+(2*7)+(1*9)=129
129 % 10 = 9
So 172154-79-9 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.
