Pentadeuterioethyl-lithium, also known as C2D5Li, is a chemical compound consisting of a lithium atom bonded to an ethyl group (C2H5) in which all five hydrogen atoms are replaced by deuterium atoms (D). Deuterium, a stable isotope of hydrogen, has one proton and one neutron in its nucleus, making it heavier than regular hydrogen. pentadeuterioethyl-lithium is primarily used in organic synthesis as a nucleophile and a strong base, often in the formation of carbon-carbon bonds and in the deprotonation of acidic protons. Due to its deuterium content, pentadeuterioethyl-lithium is also utilized in the synthesis of deuterated compounds, which are important in various fields, including pharmaceuticals and materials science, as they can provide insights into reaction mechanisms and alter the physical properties of molecules.

1629-55-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1629-55-6 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 5 respectively.
Calculate Digit Verification of CAS Registry Number 1629-55:
(6*1)+(5*6)+(4*2)+(3*9)+(2*5)+(1*5)=86
86 % 10 = 6
So 1629-55-6 is a valid CAS Registry Number.
