Uses
Used in Photographic Developing:
Ammonium sulfide is used as a reducing agent in photographic developing for its ability to react with silver halides, enabling the formation of visible images on photographic film or paper.
Used in Soil Testing:
In soil testing, ammonium sulfide is used as a source of ammonium to determine the availability of nitrogen in the soil, which is essential for plant growth and development.
Used in Textiles:
Ammonium sulfide is used in the textile industry as a reducing agent for dyeing and printing processes, as well as in the processing of certain types of fibers, such as rayon and silk. Its reducing properties help in the fixation of dyes and the alteration of fiber properties.
While not highly toxic, exposure to ammonium sulfide can cause irritation in the eyes, skin, and respiratory tract, necessitating proper handling and safety measures during its use in various applications.
Check Digit Verification of cas no
The CAS Registry Mumber 12135-77-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,1,3 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 12135-77:
(7*1)+(6*2)+(5*1)+(4*3)+(3*5)+(2*7)+(1*7)=72
72 % 10 = 2
So 12135-77-2 is a valid CAS Registry Number.
