General Description
(S)-(-)-N-(1-phenylethyl)succinamic acid is a chemical compound with a molecular formula of C12H15NO3. It is a chiral compound, meaning it has a non-superposable mirror image, and is often used as a chiral resolving agent in enantiomeric separations. The compound has a wide range of applications in the pharmaceutical and chemical industries, including as an intermediate in the synthesis of various pharmaceuticals and in the production of chiral drugs. It is also used in the preparation of chiral ligands for asymmetric catalysis and as a resolving agent in the separation of racemic mixtures. Additionally, it has found use in the development of chiral stationary phases for high-performance liquid chromatography (HPLC) and in the production of optically pure compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 21752-34-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,5 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 21752-34:
(7*2)+(6*1)+(5*7)+(4*5)+(3*2)+(2*3)+(1*4)=91
91 % 10 = 1
So 21752-34-1 is a valid CAS Registry Number.
