18145-74-9 Usage
General Description
(2,2-dichloro-1,1-diethoxy-ethyl)silane, also known as DDES, is a chemical compound primarily used as a silylating agent in organic synthesis. This clear, colorless liquid is derived from the reaction between 1,1-dichloroethane and diethylsilane. DDES is a versatile reagent that is commonly employed for the introduction of silyl groups in organic molecules, which can enhance their stability, volatility, and reactivity. It is also utilized in the production of various silicon-based materials and as a precursor in the synthesis of siloxane polymers and silicone resins. Additionally, DDES is known for its high reactivity with a wide range of functional groups, making it an important tool in the field of organic chemistry. However, it should be handled with caution due to its potential hazards as a flammable and corrosive substance.
Check Digit Verification of cas no
The CAS Registry Mumber 18145-74-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,1,4 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 18145-74:
(7*1)+(6*8)+(5*1)+(4*4)+(3*5)+(2*7)+(1*4)=109
109 % 10 = 9
So 18145-74-9 is a valid CAS Registry Number.
