General Description
The chemical "2-[[(4R)-4-[(3R,5R,8R,9S,10S,13R,14S,17R)-3-hydroxy-10,13-dimethyl-2,3,4,5,6,7,8,9,11,12,14,15,16,17-tetradecahydro-1H-cyclopenta[a]phenanthren-17-yl]pentanoyl]amino]ethanesulfonic acid" is a complex compound with a molecular structure that includes a cyclopenta[a]phenanthren core, a pentanoyl group, amino and ethanesulfonic acid moieties. It is an amino acid derivative with a steroid backbone, and it may have potential biological or pharmaceutical applications. Its specific properties and functions would need to be further investigated through research and testing.
Check Digit Verification of cas no
The CAS Registry Mumber 516-90-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 516-90:
(5*5)+(4*1)+(3*6)+(2*9)+(1*0)=65
65 % 10 = 5
So 516-90-5 is a valid CAS Registry Number.

An improved procedure for the synthesis of glycine and taurine conjugates of bile acids
Tserng,Hachey,Klein
, p. 404 - 407 (2007/10/06)
Glycine and taurine conjugates of 5β cholanic acids have been synthesized using improved procedures based on the peptide coupling reagent, N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline. The conjugates are obtained in chromatographically pure form in yields higher than 90%. The use of this procedure in the large scale preparation of choly[1,2 13C2]glycine is described.
