279228-81-8 Usage
General Description
BP 34 is a chemical additive used in the petroleum industry, particularly in oil drilling and production. Also known as Baroid 34, it is a highly effective oil-based drilling fluid additive that is designed to improve the lubricating properties of the drilling mud. This helps to reduce friction and heat during the drilling process, and also helps to prevent the occurrence of differential sticking. BP 34 is composed of a mixture of high-quality base oil and extremely pure hydrophobic silica, which gives it an excellent lubricity and thermal stability. It is also environmentally friendly and non-toxic, making it a preferred choice for use in drilling operations.
Check Digit Verification of cas no
The CAS Registry Mumber 279228-81-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,9,2,2 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 279228-81:
(8*2)+(7*7)+(6*9)+(5*2)+(4*2)+(3*8)+(2*8)+(1*1)=178
178 % 10 = 8
So 279228-81-8 is a valid CAS Registry Number.
