7778-41-8 Usage
Uses
Used in Fungicide Industry:COPPER(II)ARSENATE is used as a fungicide for limited purposes due to its ability to control and prevent fungal growth. It is particularly effective against a range of fungal diseases that can damage crops and plants.
Used in Wood Preservation Industry:
In the wood preservation industry, COPPER(II)ARSENATE is used as a preservative to protect wood from decay, fungi, and insects. Its application helps extend the lifespan of wooden structures and materials by preventing biological degradation.
Used as an Antifouling Pigment:
COPPER(II)ARSENATE is also utilized as an antifouling pigment in the marine industry. It helps prevent the growth of marine organisms, such as algae and barnacles, on the surfaces of boats, ships, and other underwater structures. This application reduces the risk of biofouling, which can negatively impact the performance and efficiency of these structures.
Check Digit Verification of cas no
The CAS Registry Mumber 7778-41-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,7 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.Calculate Digit Verification of CAS Registry Number 7778-41:
(6*7)+(5*7)+(4*7)+(3*8)+(2*4)+(1*1)=138
138 % 10 = 8
So 7778-41-8 is a valid CAS Registry Number.
