Analytical methods
Gas chromatography-mass spectrometry (GC-MS) and high-performance liquid chromatography (HPLC) are commonly used for the detection and quantification of 13(H)-indeno[1,2-c]phenanthrene in environmental samples.
Check Digit Verification of cas no
The CAS Registry Mumber 212-54-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,1 and 2 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 212-54:
(5*2)+(4*1)+(3*2)+(2*5)+(1*4)=34
34 % 10 = 4
So 212-54-4 is a valid CAS Registry Number.
