17998-91-3 Usage
General Description
Methylphenyldiacetoxysilane is a chemical compound that belongs to the group of silanes, which are silicon-based organic compounds. It is commonly used as a coupling agent and adhesion promoter in the production of silicone sealants, adhesives, and coatings. This chemical contains two acetoxysilane groups, which makes it highly reactive with hydroxyl-containing surfaces, such as glass, metal, and various polymers. Methylphenyldiacetoxysilane is known for its ability to improve the bonding strength and durability of silicone-based materials, making it a valuable ingredient in the manufacturing of various industrial and consumer products. However, it should be handled with care due to its potential hazards if not used properly.
Check Digit Verification of cas no
The CAS Registry Mumber 17998-91-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,9,9 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 17998-91:
(7*1)+(6*7)+(5*9)+(4*9)+(3*8)+(2*9)+(1*1)=173
173 % 10 = 3
So 17998-91-3 is a valid CAS Registry Number.
