123093-85-6 Usage
Description
Calcium metaphosphate, also known as Ca(PO3)2, is a vitreous flake material formed by treating phosphorus rock with gaseous phosphorus pentoxide (P2O5) or by burning elemental phosphorus with calcium oxide at high temperatures in the presence of oxygen. It contains about 72% phosphorus pentoxide and is not water-soluble but hydrolyzes slowly to form water-soluble compounds. More than 98% of phosphorus pentoxide (P2O5) in calcium metaphosphate is soluble in neutral ammonium citrate.
Uses
Used in Agricultural Applications:
Calcium metaphosphate is used as a fertilizer for providing phosphorus to crops. However, its use is limited due to its dependence on elemental phosphorus and its slow hydrolysis rate in the soil, which is not suitable for short-duration crops (less than 90 days).
Check Digit Verification of cas no
The CAS Registry Mumber 123093-85-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,3,0,9 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 123093-85:
(8*1)+(7*2)+(6*3)+(5*0)+(4*9)+(3*3)+(2*8)+(1*5)=106
106 % 10 = 6
So 123093-85-6 is a valid CAS Registry Number.
