Nepheline, a naturally occurring mineral, is an important industrial source of alkalis and is primarily composed of sodium and potassium aluminum silicates. It is often found in igneous rocks and is used in the production of glass, ceramics, and as a source of potash fertilizer. The chemical formula for nepheline can be represented as (Na,K)2O.Al2O3.2SiO2.6H2O, indicating its complex structure. This mineral is valued for its ability to contribute to various industrial processes, particularly in the manufacture of certain types of glass that require its unique composition to achieve specific properties.
The CAS Registry Mumber 1302-72-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,0 and 2 respectively; the second part has 2 digits, 7 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1302-72: (6*1)+(5*3)+(4*0)+(3*2)+(2*7)+(1*2)=43 43 % 10 = 3 So 1302-72-3 is a valid CAS Registry Number.
