68515-96-8 Usage
General Description
Sulfur AA Standard refers to a chemical standard used in analytical chemistry to calibrate and standardize the measurement of sulfur content in various substances. It is typically utilized in atomic absorption spectroscopy (AA) to ensure the accuracy and precision of sulfur analysis. The Sulfur AA Standard is a high-purity solution of sulfur compound(s), designed to be used for the preparation of calibration standards and quality control samples. Its exact composition and concentration may vary depending on the specific application and requirements of the analysis, but it is commonly used as a reference material to facilitate the accurate quantification of sulfur in different samples.
Check Digit Verification of cas no
The CAS Registry Mumber 68515-96-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,5,1 and 5 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 68515-96:
(7*6)+(6*8)+(5*5)+(4*1)+(3*5)+(2*9)+(1*6)=158
158 % 10 = 8
So 68515-96-8 is a valid CAS Registry Number.
