65997-18-4 Usage
General Description
Lead bisilicate is a chemical compound with a formula of PbO2·2SiO2. It is primarily used in industry as a frit in ceramic glazes, with its key role being to lower the glaze’s melting point. However, due to the potential health risks of lead exposure, usage of lead bisilicate has decreased significantly over time. Lead exposure can cause neurological damage and is particularly hazardous to children. Therefore, in many regions, laws have been established to regulate its use or to phase it out entirely, particularly in products intended for food use. Despite this, lead bisilicate may still feature in specialized or traditional pottery methods, or in non-dinnerware ceramics such as tiles or ornaments.
Check Digit Verification of cas no
The CAS Registry Mumber 65997-18-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,9,9 and 7 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 65997-18:
(7*6)+(6*5)+(5*9)+(4*9)+(3*7)+(2*1)+(1*8)=184
184 % 10 = 4
So 65997-18-4 is a valid CAS Registry Number.
