Zr(ethyl-β-oxy-β-phenylbutyrate)4, also known as zirconium ethyl-β-oxy-β-phenylbutyrate, is a complex organic compound with the chemical formula C36H44O8Zr. It is a type of zirconium-based catalyst, commonly used in the polymerization of olefins, such as ethylene and propylene, to produce polyolefins. The compound consists of a central zirconium atom coordinated to four ethyl-β-oxy-β-phenylbutyrate ligands, which are bidentate, meaning they bind to the metal center through two donor atoms. This structure allows for the formation of a stable, active catalyst that can efficiently control the polymerization process, leading to the production of high-quality polyolefins with desired properties.

Check Digit Verification of cas no

The CAS Registry Mumber 74437-24-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,3 and 7 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74437-24:
(7*7)+(6*4)+(5*4)+(4*3)+(3*7)+(2*2)+(1*4)=134
134 % 10 = 4
So 74437-24-4 is a valid CAS Registry Number.
