6689-22-1 Usage
General Description
1,3-Diphenyl-1,3-dimethyldisiloxane is a chemical compound with the molecular formula C16H20OSi2. It is a type of disiloxane with two silicon atoms bonded to oxygen atoms and substituted with phenyl and methyl groups. 1,3-DIPHENYL-1,3-DIMETHYLDISILOXANE is primarily used as a crosslinker in the synthesis of silicones, which are widely used in various industrial and consumer applications such as adhesives, sealants, and lubricants. It serves as a valuable building block in the production of polymers and materials with specific properties such as heat and chemical resistance, electrical insulation, and water repellency. Additionally, it can function as a coupling agent in organic synthesis and as a protective group in organic reactions due to its stability and reactivity.
Check Digit Verification of cas no
The CAS Registry Mumber 6689-22-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,8 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6689-22:
(6*6)+(5*6)+(4*8)+(3*9)+(2*2)+(1*2)=131
131 % 10 = 1
So 6689-22-1 is a valid CAS Registry Number.
