Yersiniose is a polysaccharide antigen found in the cell wall of Yersinia pestis, the bacterium responsible for causing plague. It is a homopolymer composed of D-talose, a rare sugar, and plays a crucial role in the virulence of the pathogen. Yersiniose is essential for the survival of Y. pestis in the flea gut, which is the primary vector for the transmission of plague. The presence of yersiniose allows the bacteria to evade the host's immune system and contributes to the pathogen's ability to cause severe infections. Understanding the structure and function of yersiniose is important for the development of new therapeutic strategies and vaccines against plague.

Check Digit Verification of cas no

The CAS Registry Mumber 89367-91-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,3,6 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 89367-91:
(7*8)+(6*9)+(5*3)+(4*6)+(3*7)+(2*9)+(1*1)=189
189 % 10 = 9
So 89367-91-9 is a valid CAS Registry Number.
