α-Trimethylsilyl-N,N-diethylacetamide, also known as TMSDEA, is a chemical compound with the molecular formula C9H21NOSi. It is a colorless liquid that is widely used as a base and a silylating agent in organic synthesis. TMSDEA is particularly effective in the deprotection of silyl ethers and in the formation of silyl enol ethers, which are crucial intermediates in many organic reactions. It is also used as a catalyst in various chemical transformations, such as the Beckmann rearrangement and the Mukaiyama aldol reaction. Due to its ability to stabilize carbocations and its mild basicity, TMSDEA is a valuable tool in the synthesis of complex organic molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 23138-65-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,1,3 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 23138-65:
(7*2)+(6*3)+(5*1)+(4*3)+(3*8)+(2*6)+(1*5)=90
90 % 10 = 0
So 23138-65-0 is a valid CAS Registry Number.
