12778-65-3 Usage
General Description
Mercury-silver (1:1) is a chemical compound consisting of a 1:1 ratio of mercury and silver atoms. It is a solid at room temperature and is commonly used in thermometers, barometers, and other scientific instruments due to its high thermal and electrical conductivity. However, it is highly toxic and can cause severe health effects if ingested or inhaled. Due to its hazardous nature, the use of mercury-silver (1:1) in consumer products has been phased out in many countries, and safer alternatives are being used instead. Nevertheless, it still has some industrial applications, such as in the production of electrical equipment and pharmaceuticals. Overall, while mercury-silver (1:1) has useful properties, its toxic nature has led to efforts to minimize its use and find safer alternatives.
Check Digit Verification of cas no
The CAS Registry Mumber 12778-65-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,7,7 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 12778-65:
(7*1)+(6*2)+(5*7)+(4*7)+(3*8)+(2*6)+(1*5)=123
123 % 10 = 3
So 12778-65-3 is a valid CAS Registry Number.
