42019-89-6 Usage
General Description
2,6-dibenzylidene-3-methylcyclohexanone is a chemical compound with the molecular formula C20H20O. It is also known as dibenzalacetone and is commonly used as a UV filter in sunscreens and cosmetic products due to its ability to absorb and block ultraviolet radiation. It is a yellow crystalline solid with a characteristic odor and is relatively stable under normal conditions. It is synthesized through the aldol condensation reaction between benzaldehyde and acetone, and its structure consists of a cyclohexanone ring with two benzylidene groups attached. In addition to its use in sunscreen, it also has potential applications in organic synthesis and as a photochromic material. However, its potential toxicity and environmental impact are areas of concern and further research is needed to fully understand its effects.
Check Digit Verification of cas no
The CAS Registry Mumber 42019-89-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,0,1 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 42019-89:
(7*4)+(6*2)+(5*0)+(4*1)+(3*9)+(2*8)+(1*9)=96
96 % 10 = 6
So 42019-89-6 is a valid CAS Registry Number.
