Colanic acid, also known as colanic acid or colanic acid, is a type of extracellular polysaccharide produced by certain bacteria, particularly Escherichia coli and Klebsiella pneumoniae. It is a high molecular weight, acidic, and heterogeneous polymer composed of repeating units of D-glucose, D-galactose, and L-rhamnose. Colanic acid plays a crucial role in bacterial biofilm formation, adhesion, and virulence, as it helps protect the bacteria from environmental stress and the host immune system. Additionally, it has been implicated in the pathogenesis of various infections, such as urinary tract infections and pneumonia. Research on colanic acid is ongoing, with potential applications in the development of new antimicrobial agents and vaccines targeting bacterial infections.

Check Digit Verification of cas no

The CAS Registry Mumber 9012-87-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,1 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 9012-87:
(6*9)+(5*0)+(4*1)+(3*2)+(2*8)+(1*7)=87
87 % 10 = 7
So 9012-87-7 is a valid CAS Registry Number.
