2,5-Diisopropyl-benzophenon, also known as 2,5-diisopropylbenzophenone, is an organic compound with the chemical formula C17H22O. It is a white crystalline solid that is insoluble in water but soluble in organic solvents. 2,5-Diisopropyl-benzophenon is primarily used as a photostabilizer in the plastics industry, particularly for polyvinyl chloride (PVC) and other polymers, to protect them from degradation caused by exposure to ultraviolet (UV) light. It functions by absorbing UV radiation and dissipating the energy as heat, thus preventing the breakdown of the polymer chains. 2,5-Diisopropyl-benzophenon is also used in the production of certain types of resins and as a chemical intermediate in the synthesis of other compounds. Due to its effectiveness and stability, it is a widely used additive in various industrial applications.

Check Digit Verification of cas no

The CAS Registry Mumber 2887-73-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,8 and 7 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2887-73:
(6*2)+(5*8)+(4*8)+(3*7)+(2*7)+(1*3)=122
122 % 10 = 2
So 2887-73-2 is a valid CAS Registry Number.
