2,2,4,4-tetramethyl-6-phenyl-6-triethylsilanyloxy-cyclotrisiloxane is a complex organosilicon compound with the molecular formula C22H42O3Si4. It is a cyclic trisiloxane, which means it consists of three silicon atoms connected in a ring, with each silicon atom bonded to an oxygen atom. The compound features two methyl groups (CH3) attached to each of the two terminal silicon atoms, and a phenyl group (C6H5) and a triethylsilanyloxy group (Si(C2H5)3O) attached to the central silicon atom. This unique structure gives the compound specific properties, such as thermal stability and low reactivity, making it useful in various applications, including as a component in silicone-based materials and as a precursor in the synthesis of other organosilicon compounds.
The CAS Registry Mumber 18415-84-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,4,1 and 5 respectively; the second part has 2 digits, 8 and 4 respectively. Calculate Digit Verification of CAS Registry Number 18415-84: (7*1)+(6*8)+(5*4)+(4*1)+(3*5)+(2*8)+(1*4)=114 114 % 10 = 4 So 18415-84-4 is a valid CAS Registry Number.
