General Description
2-Ethoxy-1-ethynyl-benzene, also known as phenyl ethynyl ether and C10H10O, is an organic compound that belongs to the class of organic compounds known as diphenyl ethers. Its structural formula is has an aromatic benzene ring, with an ethoxy group (C2H5O-) and an ethynyl group (-C≡CH) attached. Due to its chemical structure, it is expected to be a lipophilic compound, which means it has the tendency to combine with or dissolve in lipids or fats. It is commonly used as an intermediate in organic synthesis and in the making of other chemicals. It needs to be handled with care as it is flammable and harmful if inhaled or swallowed, and it can cause skin and eye irritation. As such, measures for personal protection are needed when handling this compound.
Check Digit Verification of cas no
The CAS Registry Mumber 90843-12-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,4 and 3 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 90843-12:
(7*9)+(6*0)+(5*8)+(4*4)+(3*3)+(2*1)+(1*2)=132
132 % 10 = 2
So 90843-12-2 is a valid CAS Registry Number.
