β-P4S5, also known as beta-phosphorus pentasulfide, is a chemical compound consisting of four phosphorus atoms and five sulfur atoms. It is a yellow-brown solid with a melting point of 300°C and a density of 2.08 g/cm3. β-P4S5 is a member of the phosphorus-sulfur system and is formed by the reaction of phosphorus and sulfur under specific conditions. β-P4S5 is insoluble in water but soluble in organic solvents like carbon disulfide and carbon tetrachloride. It has potential applications in the synthesis of various phosphorus-containing compounds and as a precursor in the production of other phosphorus-sulfur compounds.

Check Digit Verification of cas no

The CAS Registry Mumber 20419-10-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,1 and 9 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 20419-10:
(7*2)+(6*0)+(5*4)+(4*1)+(3*9)+(2*1)+(1*0)=67
67 % 10 = 7
So 20419-10-7 is a valid CAS Registry Number.
