2,6,7-Trioxa-1,4-diphosphabicyclo[2.2.2]octane 1,4-dioxide, also known as P4O10 or tetraphosphorus decoxide, is a chemical compound consisting of four phosphorus atoms and ten oxygen atoms. It is a white, crystalline solid that is insoluble in water and has a molecular formula of P4O10. 2,6,7-Trioxa-1,4-diphosphabicyclo[2.2.2]octane1,4-dioxide is an important intermediate in the production of various phosphorus-containing chemicals, such as phosphoric acid and phosphorus pentoxide. It is also used as a desiccant and a drying agent in industrial processes. Due to its reactivity with water, it is essential to handle P4O10 with caution and store it in a dry environment to prevent the formation of phosphoric acid.

4726-80-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 4726-80-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,2 and 6 respectively; the second part has 2 digits, 8 and 0 respectively.Calculate Digit Verification of CAS Registry Number 4726-80:
(6*4)+(5*7)+(4*2)+(3*6)+(2*8)+(1*0)=101
101 % 10 = 1
So 4726-80-1 is a valid CAS Registry Number.
