S-Benzyl-2-butyl-DL-cysteine is an organic compound with the chemical formula C11H19NO2S. It is a derivative of the amino acid cysteine, featuring a benzyl group attached to the sulfur atom and a butyl chain extending from the beta-carbon. S-Benzyl-2-butyl-DL-cysrein is a chiral molecule, meaning it has a non-superimposable mirror image, and is presented here as the racemic mixture (DL), containing equal parts of both the R and S enantiomers. It is used in various chemical and pharmaceutical applications, such as the synthesis of complex molecules and the study of chiral interactions.

Check Digit Verification of cas no

The CAS Registry Mumber 2190-89-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,9 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2190-89:
(6*2)+(5*1)+(4*9)+(3*0)+(2*8)+(1*9)=78
78 % 10 = 8
So 2190-89-8 is a valid CAS Registry Number.
