Sodium fluoride hydrofluoride is a combination of two distinct chemical compounds, sodium fluoride (NaF) and hydrofluoric acid (HF). Sodium fluoride is a relatively safe compound with low toxicity, commonly used in toothpaste and water fluoridation processes for its dental health benefits, particularly in cavity prevention. On the other hand, hydrofluoric acid is a highly dangerous and corrosive acid, used in processes such as glass etching and mineral digestion. Both chemicals contain the element fluorine but exhibit significantly different levels of risk and applications.

51273-71-3 Usage
Uses
Used in Dental Health:Sodium fluoride hydrofluoride is used as a dental health agent for its cavity prevention properties. Sodium fluoride, being a component of this combination, strengthens tooth enamel and helps prevent dental caries.
Used in Water Fluoridation:
Sodium fluoride hydrofluoride is utilized as a water treatment agent to fluoridate water supplies, providing the population with the dental health benefits of fluoride.
Used in Glass Etching:
Hydrofluoric acid, a component of sodium fluoride hydrofluoride, is used as an etching agent in the glass industry to create decorative patterns and designs on glass surfaces.
Used in Mineral Digestion:
Hydrofluoric acid is employed as a digestion agent in the process of breaking down minerals for analysis or other applications, due to its ability to dissolve certain types of mineral matter.
Check Digit Verification of cas no
The CAS Registry Mumber 51273-71-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,2,7 and 3 respectively; the second part has 2 digits, 7 and 1 respectively.Calculate Digit Verification of CAS Registry Number 51273-71:
(7*5)+(6*1)+(5*2)+(4*7)+(3*3)+(2*7)+(1*1)=103
103 % 10 = 3
So 51273-71-3 is a valid CAS Registry Number.
