83998-91-8 Usage
General Description
DL-ALANINE-2,3,3,3-D4 is a deuterated analogue of DL-alanine, which is a non-essential amino acid and a key component in the synthesis of proteins. The "2,3,3,3-D4" designation indicates that four hydrogen atoms in the molecule have been replaced with deuterium atoms, which are heavier isotopes of hydrogen. Deuterated compounds are commonly used in scientific research and pharmaceutical development for various purposes, including as internal standards for mass spectrometry and nuclear magnetic resonance spectroscopy. DL-ALANINE-2,3,3,3-D4 has applications in isotopic labeling studies, metabolic research, and as a reference material for accurate quantification of alanic acid in biological samples.
Check Digit Verification of cas no
The CAS Registry Mumber 83998-91-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,9 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 83998-91:
(7*8)+(6*3)+(5*9)+(4*9)+(3*8)+(2*9)+(1*1)=198
198 % 10 = 8
So 83998-91-8 is a valid CAS Registry Number.
