4-Fluor-N-nitroso-diphenylamin, also known as 4-fluoro-N-nitroso-N-phenylbenzenamine, is an organic compound with the chemical formula C12H9FN2O. It is a derivative of diphenylamine, featuring a fluorine atom at the 4-position and a nitroso group (-N=O) attached to the nitrogen atom. This yellow crystalline solid is sensitive to light and heat, and it is used as an intermediate in the synthesis of various pharmaceuticals, agrochemicals, and dyes. Due to its potential reactivity and the presence of a nitroso group, it is important to handle 4-Fluor-N-nitroso-diphenylamin with care, following appropriate safety protocols.

Check Digit Verification of cas no

The CAS Registry Mumber 1545-84-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 5 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1545-84:
(6*1)+(5*5)+(4*4)+(3*5)+(2*8)+(1*4)=82
82 % 10 = 2
So 1545-84-2 is a valid CAS Registry Number.
