104518-25-4 Usage
General Description
1-{2-[2-(2-{2-[2-(2-Bromo-ethoxy)-ethoxy]-ethoxy}-ethoxy)-ethoxy]-ethoxy}-2-methoxy-ethane is a long-chain chemical compound that features a bromo-ethoxy group interspersed with multiple ethoxy groups. The bromo-ethoxy aspect of the compound indicates the presence of a bromine atom and an oxygen atom, both attached to an ethyl group. In turn, this group is connected to other similar ethyl and oxygen units or an end methoxy group. This pattern of recurring ethoxy functionality linked together with an end methoxy group and the interruption of bromo-ethoxy group creates a complex, long-chain structure. Despite its complex name, the structure is essentially a series of hydrocarbon chains linked together by ether linkages and a halogenated ethoxy group. The properties, physical or chemical, of this compound will largely be influenced by its long chain structure and the functional groups, evident in its chemical name.
Check Digit Verification of cas no
The CAS Registry Mumber 104518-25-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,5,1 and 8 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104518-25:
(8*1)+(7*0)+(6*4)+(5*5)+(4*1)+(3*8)+(2*2)+(1*5)=94
94 % 10 = 4
So 104518-25-4 is a valid CAS Registry Number.
