3. It is used for microanalysis of rubidium, cesium and in the determination of alkaloids. Usually used as a harbinger for the preparation of gold (Au) nanoparticles. It is used in the control rods of nuclear reactors and in the manufacturing of electric light filaments.
General Description
The embryotoxicity of gold salt (HAuCl4 · 3H2O) is weaker than the embryotoxicities of a number of other nanoparticles used infor biomedical applications.
Check Digit Verification of cas no
The CAS Registry Mumber 16961-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,6,9,6 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 16961-25:
(7*1)+(6*6)+(5*9)+(4*6)+(3*1)+(2*2)+(1*5)=124
124 % 10 = 4
So 16961-25-4 is a valid CAS Registry Number.
