Bis-<4-(4-fluor-benzyliden)-butyryl>-peroxid, also known as bis(4-(4-fluorobenzylidene)butyryl) peroxide, is a chemical compound with the molecular formula C20H18F2O4. It is a type of peroxide, specifically a diacyl peroxide, which is characterized by the presence of two acyl groups (in this case, 4-(4-fluorobenzylidene)butyryl) bonded to an oxygen-oxygen single bond. Bis-<4-(4-fluor-benzyliden)-butyryl>-peroxid is often used as a polymerization initiator or a cross-linking agent in various industrial applications, such as the production of plastics and rubber. Due to its peroxide nature, it is sensitive to heat and shock, and therefore, it must be handled with caution to prevent decomposition and potential hazards.
The CAS Registry Mumber 5723-99-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,7,2 and 3 respectively; the second part has 2 digits, 9 and 9 respectively. Calculate Digit Verification of CAS Registry Number 5723-99: (6*5)+(5*7)+(4*2)+(3*3)+(2*9)+(1*9)=109 109 % 10 = 9 So 5723-99-9 is a valid CAS Registry Number.
