DIPHENYLDIACETOXYSILANE, with the molecular formula C18H18O4Si, is a silane coupling agent characterized by its colorless to pale yellow liquid appearance and a sharp, pungent odor. It is a highly reactive chemical compound that serves as a crosslinking agent in the production of silicone rubbers and resins, and also functions as an intermediate in the synthesis of other organosilicon compounds. Due to its reactivity, it requires careful handling to prevent irritation to the skin, eyes, and respiratory system, necessitating storage in well-ventilated areas away from heat, flames, and incompatible materials.

Check Digit Verification of cas no

The CAS Registry Mumber 2565-07-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,6 and 5 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2565-07:
(6*2)+(5*5)+(4*6)+(3*5)+(2*0)+(1*7)=83
83 % 10 = 3
So 2565-07-3 is a valid CAS Registry Number.

Anti-Markovnikov terminal and gem-olefin hydrosilylation using a κ4-diimine nickel catalyst: selectivity for alkene hydrosilylation over ether C-O bond cleavage

Rock, Christopher L.,Trovitch, Ryan J.

supporting information, p. 461 - 467 (2019/01/09)

The phosphine-substituted α-diimine Ni precursor, (Ph2PPrDI)Ni, has been found to catalyze alkene hydrosilylation in the presence of Ph2SiH2 with turnover frequencies of up to 124 h?1 at 25 °C (990 h?1 at 60 °C). Moreover, the selective hydrosilylation of allylic and vinylic ethers has been demonstrated, even though (Ph2PPrDI)Ni is known to catalyze allyl ester C-O bond hydrosilylation. At 70 °C, this catalyst has been found to mediate the hydrosilylation of ten different gem-olefins, with turnover numbers of up to 740 under neat conditions. Prior and current mechanistic observations suggest that alkene hydrosilylation takes place though a Chalk-Harrod mechanism following phosphine donor dissociation.
