21548-73-2 Usage

Physical Properties

Grayish-black orthogonal crystals or powder; density 7.23 g/cm3; Moh’s hardness 2.3; melts at 825°C; insoluble in water; soluble in nitric and sulfuric acids.

Occurrence and Uses

Silver sulfide occurs in nature as mineral argentite. It is used in ceramics.

Preparation

Mineral argentite is mined from mineral deposits, crushed, ground, and washed for use. In the laboratory, silver sulfide is obtained by passing hydrogen sulfide gas through a solution of silver nitrate. The precipitate is washed with hot water.

Check Digit Verification of cas no

The CAS Registry Mumber 21548-73-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,4 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21548-73:
(7*2)+(6*1)+(5*5)+(4*4)+(3*8)+(2*7)+(1*3)=102
102 % 10 = 2
So 21548-73-2 is a valid CAS Registry Number.
