61789-36-4 Usage
General Description
Calcium naphthenate is a chemical compound primarily formed in crude oil development, when calcium ions in brine waters come into contact with naphthenic acids present in petroleum. Characterized by a soap-like, sticky consistency, these deposits can cause significant flow issues and equipment malfunctions in oil pipelines, significantly impacting oil processing and extraction efficiency. Beyond this industrial context, exposure to calcium naphthenate is generally considered hazardous, with potential risks including skin and eye irritation, respiratory issues, and harmful environmental impacts if not carefully managed.
Check Digit Verification of cas no
The CAS Registry Mumber 61789-36-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,7,8 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 61789-36:
(7*6)+(6*1)+(5*7)+(4*8)+(3*9)+(2*3)+(1*6)=154
154 % 10 = 4
