3,3-Dimercaptoquinuclidine, also known as DMQ, is a chemical compound with the molecular formula C8H16N2S2. It is a colorless, crystalline solid that is soluble in water and various organic solvents. DMQ is primarily used as a chelating agent, particularly for heavy metal ions such as mercury, lead, and cadmium. It forms stable complexes with these metals, which can then be removed from the environment or treated waste. The compound is also used in the synthesis of other organic compounds and as a reagent in analytical chemistry. Due to its potential toxicity and environmental impact, DMQ is handled with care and is subject to regulatory controls in many countries.
The CAS Registry Mumber 4029-14-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,2 and 9 respectively; the second part has 2 digits, 1 and 4 respectively. Calculate Digit Verification of CAS Registry Number 4029-14: (6*4)+(5*0)+(4*2)+(3*9)+(2*1)+(1*4)=65 65 % 10 = 5 So 4029-14-5 is a valid CAS Registry Number.
