4-Ethyltoluene-α,α,α-D3 is a deuterated chemical compound, which means it contains deuterium atoms (an isotope of hydrogen with one neutron and one proton) in place of some of its hydrogen atoms. Specifically, 4-ETHYLTOLUENE-ALPHA,ALPHA,ALPHA-D3 has three deuterium atoms in the α (alpha) positions, which are the positions directly attached to the benzene ring in the toluene molecule. The parent compound, 4-ethyltoluene, is an aromatic hydrocarbon with a methyl group at the 4-position and an ethyl group at the same position on the benzene ring. Deuterated compounds like 4-ethyltoluene-α,α,α-D3 are often used in scientific research, particularly in spectroscopy and isotope labeling studies, to help distinguish between different molecules and understand their behavior in various chemical reactions.

939-98-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 939-98-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 9 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 939-98:
(5*9)+(4*3)+(3*9)+(2*9)+(1*8)=110
110 % 10 = 0
So 939-98-0 is a valid CAS Registry Number.
