Silane, bis(1,1-dimethylethoxy)methyl-, also known as bis(1,1-dimethylethoxy)methylsilane or (CH3)3COSi(CH3)3, is an organosilicon compound characterized by its molecular formula C7H18OSi. This colorless, volatile liquid is a derivative of silane, with two 1,1-dimethylethoxy groups (also known as tert-butoxy groups) attached to a central methyl group. It is primarily used as a coupling agent in the production of composite materials, enhancing the adhesion between inorganic fillers and organic polymers. Additionally, it serves as a cross-linking agent in the synthesis of silicone rubber and other silicone-based materials, contributing to improved mechanical properties and thermal stability. Due to its reactivity, it is essential to handle Silane, bis(1,1-dimethylethoxy)methyl- with care, typically under an inert atmosphere to prevent unwanted side reactions.

7489-74-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 7489-74-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,8 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 7489-74:
(6*7)+(5*4)+(4*8)+(3*9)+(2*7)+(1*4)=139
139 % 10 = 9
So 7489-74-9 is a valid CAS Registry Number.
