61971-47-9 Usage
Description
Clerici solution is an aqueous solution consisting of equal parts of thallium formate (TI(HCO2)) and thallium malonate (TI(C3H3O4)). It has valuable application in mineralogy, being capable of separate minerals by density with a traditional flotationmethod. Its advantages include transparency and an easily controllable density in the range 1–5 g/cm3. At the same time, floatation in cleric solution for density measuring is one of the most effective methods in the determination of the specific gravity of small mineral grains.

Check Digit Verification of cas no
The CAS Registry Mumber 61971-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,9,7 and 1 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 61971-47:
(7*6)+(6*1)+(5*9)+(4*7)+(3*1)+(2*4)+(1*7)=139
139 % 10 = 9
So 61971-47-9 is a valid CAS Registry Number.
