General Description
(5-chlorothiophen-2-yl)acetonitrile is a chemical compound with a molecular formula C8H6ClNS. It is a nitrile derivative of 5-chlorothiophene, which is a heterocyclic compound containing a sulfur atom and a chlorine atom. The presence of the acetonitrile group in the molecule makes it a useful intermediate for the synthesis of various organic compounds, including pharmaceuticals, agrochemicals, and other fine chemicals. The compound may have applications in organic chemistry as a building block for the preparation of complex molecules. It is important to handle this chemical with caution and follow appropriate safety measures, as nitriles can be toxic and irritating to the skin, eyes, and respiratory system.
Check Digit Verification of cas no
The CAS Registry Mumber 42520-90-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,2 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 42520-90:
(7*4)+(6*2)+(5*5)+(4*2)+(3*0)+(2*9)+(1*0)=91
91 % 10 = 1
So 42520-90-1 is a valid CAS Registry Number.
