Used in Analytical Chemistry:
(2-Aminoethyl)diphenylphosphine oxide is used as a chelating agent for the determination of metal ions in complex samples. Its ability to form stable complexes with metal ions makes it a valuable tool in analytical chemistry for accurate metal ion analysis.
Check Digit Verification of cas no
The CAS Registry Mumber 33921-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,3,9,2 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 33921-17:
(7*3)+(6*3)+(5*9)+(4*2)+(3*1)+(2*1)+(1*7)=104
104 % 10 = 4
So 33921-17-4 is a valid CAS Registry Number.
