Description
Cassiterite (SnO2) is a naturally occurring mineral that is a yellow, brown, or black form of tin(IV) oxide. It forms tetragonal, often twinned, crystals and is the principal ore of tin. Cassiterite can be found in hydrothermal veins, metasomatic deposits associated with acidic igneous rocks, and in alluvial (placer) deposits. The main producers of this mineral are Malaysia, Indonesia, the Democratic Republic of Congo, and Nigeria.
Uses

Check Digit Verification of cas no
The CAS Registry Mumber 1317-45-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,1 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1317-45:
(6*1)+(5*3)+(4*1)+(3*7)+(2*4)+(1*5)=59
59 % 10 = 9
So 1317-45-9 is a valid CAS Registry Number.
InChI:InChI=1/2O.Sn/rO2Sn/c1-3-2
