Graphite, a form of carbon, is a key component in this set of chemicals due to its excellent electrical and thermal conductivity. The fusion crucible, made from graphite, is designed to withstand high temperatures and is used for melting and holding materials during chemical reactions. The drillpoint, also made of graphite, is a precision tool used for drilling small holes in various materials. The term "unpurified" suggests that the graphite may contain impurities, which could affect its performance in certain applications. Lastly, the volume of 7.5cc refers to the capacity of the container or the amount of material being used, which is crucial for accurate measurements in chemical processes. Together, these chemicals and tools are essential for various industrial and laboratory applications, particularly those involving high temperatures and precision work.
The CAS Registry Mumber 2319-55-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,3,1 and 9 respectively; the second part has 2 digits, 5 and 5 respectively. Calculate Digit Verification of CAS Registry Number 2319-55: (6*2)+(5*3)+(4*1)+(3*9)+(2*5)+(1*5)=73 73 % 10 = 3 So 2319-55-3 is a valid CAS Registry Number.
