D-Cystathionine is a non-protein amino acid that plays a significant role in the metabolism of sulfur-containing amino acids, such as cysteine and methionine. It is an essential component of the transsulfuration pathway, which is involved in the conversion of homocysteine to cysteine. This conversion is crucial for the synthesis of glutathione, a powerful antioxidant that helps protect cells from oxidative stress and damage. D-Cystathionine is also involved in the synthesis of taurine, another important antioxidant. Due to its role in these metabolic pathways, D-Cystathionine has been studied for its potential benefits in maintaining cardiovascular health, supporting the immune system, and promoting overall well-being.

Check Digit Verification of cas no

The CAS Registry Mumber 2998-83-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,9 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2998-83:
(6*2)+(5*9)+(4*9)+(3*8)+(2*8)+(1*3)=136
136 % 10 = 6
So 2998-83-6 is a valid CAS Registry Number.
