Colominic acid, also known as 5-keto-3-deoxy-D-glycero-D-galacto-nononic acid, is a unique sugar acid that is a component of the bacterial cell wall in certain Gram-negative bacteria. It is structurally similar to the sugar acids found in the cell walls of Gram-positive bacteria, such as kdonoic acid and legionaminic acid. Colominic acid plays a crucial role in the formation and stability of the outer membrane of these bacteria, contributing to their resistance to antibiotics and the host's immune system. It is also a target for the development of new antibacterial agents, as it is essential for the survival of the bacteria. The study of colominic acid and its role in bacterial cell wall synthesis is important for understanding the pathogenesis of infections caused by Gram-negative bacteria and for the development of novel therapeutic strategies.

Check Digit Verification of cas no

The CAS Registry Mumber 9013-15-4 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 3 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 9013-15:
(6*9)+(5*0)+(4*1)+(3*3)+(2*1)+(1*5)=74
74 % 10 = 4
So 9013-15-4 is a valid CAS Registry Number.
