50965-66-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 50965-66-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,0,9,6 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 50965-66:
(7*5)+(6*0)+(5*9)+(4*6)+(3*5)+(2*6)+(1*6)=137
137 % 10 = 7
So 50965-66-7 is a valid CAS Registry Number.

The influence of the organolithium reagent nature on the possibility of the O→Csp migration of the R3Si group in propynes HC≡CCH2OSiR3

Novokshonov,Medvedeva,Mareev

, p. 2264 - 2268 (2018/03/25)

A possibility of the O→Csp 1,4-migration of the R3Si group in silyl ethers of terminal acetylenic alcohols upon treatment with organolithium reagents (RLi) was studied. In the case of 3-trimethylsilyloxypropyne, depending on the nature of RLi, the heterolysis of the Si—O bond occurs either by the action of acetylide formed as a result of deprotonation with the formation of 3-trimethylsilylprop-2-yn-1-ol trimethylsilyl ether, or by the action of the metalation agent with the formation of propargyl alcohol. The realization of the O→Csp 1,4-migration of the Me3Si group requires the use of mild organolithium reagents (lithium hexamethyldisilazanide and diisopropylamide). Silyl ethers having steric hindrance at the carbon atom bonded to the reaction center or around the silicon atom do not react with the studied organolithium reagents.
