11120-22-2 Usage
Description
Lead silicate, also known as lead bisilicate, is a pale yellow powder with the chemical formula PbO·0.03Al2O3 · 1.95SiO2. It is insoluble in water and has a composition of 65% PbO, 1% Al2O3, and 34% SiO2 by weight. Lead silicate is available in granular form, less than 1.68 mm (10 mesh), and ground form, with 88% passing through 44 μm (325 mesh). It was specifically developed as a low solubility source of lead in glazes, where its high viscosity and low volatility are crucial properties.
Uses

Check Digit Verification of cas no
The CAS Registry Mumber 11120-22-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,1,1,2 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 11120-22:
(7*1)+(6*1)+(5*1)+(4*2)+(3*0)+(2*2)+(1*2)=32
32 % 10 = 2
So 11120-22-2 is a valid CAS Registry Number.
