(+/-)-(2S,4R)-4-hydroxyglutamic acid, also known as 4-hydroxyglutamate, is a non-proteinogenic amino acid with the chemical formula C5H9NO5. It is an isomer of glutamic acid, featuring a hydroxyl group (-OH) at the 4-position instead of a hydrogen atom. (+/-)-(2S,4R)-4-hydroxyglutamic acid is a chiral molecule, meaning it has two enantiomeric forms: (2S,4R) and (2S,4S). 4-hydroxyglutamic acid plays a significant role in various biological processes, such as neurotransmission and cellular signaling, and has potential applications in pharmaceuticals and biotechnology.
The CAS Registry Mumber 6141-40-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,1,4 and 1 respectively; the second part has 2 digits, 4 and 0 respectively. Calculate Digit Verification of CAS Registry Number 6141-40: (6*6)+(5*1)+(4*4)+(3*1)+(2*4)+(1*0)=68 68 % 10 = 8 So 6141-40-8 is a valid CAS Registry Number.
