4,4-Diacetamido stilbene-2,2-disulfonic acid, also known as DIDS, is a synthetic chemical compound with the molecular formula C16H16N2O8S2. It is a potent inhibitor of anion exchangers, particularly the band 3 protein, which plays a crucial role in the transport of chloride ions across cell membranes. DIDS is widely used in biological research to study the function of anion channels and transporters in various cell types. It is also employed as a tool to investigate the role of anion transport in physiological processes such as cell volume regulation, pH balance, and ion homeostasis. DIDS is known for its ability to block the chloride conductance in red blood cells and has been used to probe the mechanisms underlying various diseases and conditions that involve altered anion transport.

Check Digit Verification of cas no

The CAS Registry Mumber 5968-56-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,6 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 5968-56:
(6*5)+(5*9)+(4*6)+(3*8)+(2*5)+(1*6)=139
139 % 10 = 9
So 5968-56-9 is a valid CAS Registry Number.
