(2,2,2-trideuterio-ethyl)-lithium, also known as lithium 2,2,2-trideuterioethanolate or lithium t-butoxide, is a chemical compound with the formula C2D7LiO. It is a deuterated version of lithium ethoxide, where the hydrogen atoms in the ethyl group are replaced with deuterium atoms. (2,2,2-trideuterio-ethyl)-lithium is primarily used as a strong base and a nucleophile in organic synthesis, particularly in reactions involving deuterium labeling. The presence of deuterium atoms in the molecule can provide valuable information about the reaction mechanism and the stability of intermediates, making it a useful tool in the study of chemical reactions.
The CAS Registry Mumber 1629-54-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,2 and 9 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 1629-54: (6*1)+(5*6)+(4*2)+(3*9)+(2*5)+(1*4)=85 85 % 10 = 5 So 1629-54-5 is a valid CAS Registry Number.
