General Description
4-Chloro-2H-pyrazol-3-ylamine is a chemical compound with the molecular formula C3H3ClN4. It belongs to the class of organic compounds known as pyrazoles, which are polycyclic aromatic compounds containing a five-membered ring with two nitrogen atoms and three carbon atoms. This specific compound features a chloro group, indicating the presence of chlorine, which is often employed in organic chemistry as a type of "leaving group." As with all chemicals, proper handling, storage, and disposal methods are required to ensure safety, particularly due to potential reactivity concerns. Its specific applications and properties may vary depending on its usage in synthetic chemistry.
Check Digit Verification of cas no
The CAS Registry Mumber 103286-54-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,2,8 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 103286-54:
(8*1)+(7*0)+(6*3)+(5*2)+(4*8)+(3*6)+(2*5)+(1*4)=100
100 % 10 = 0
So 103286-54-0 is a valid CAS Registry Number.
