The given chemical formula represents a complex organic compound, which is a cation-anion pair. The cation is a derivative of an amine, specifically a diborane-substituted ethylenediamine, with the formula {(C6H4B(OH)2CH2)2N(C2H5)(C6H5)}+. This cation has two phenyl rings (C6H5), two boron atoms each bonded to two hydroxyl groups (OH) and a methylene group (CH2), and an ethyl group (C2H5) attached to the nitrogen atom. The anion is a chloride ion, Cl-. The overall compound is a salt, formed by the combination of the cation and the chloride anion.
The CAS Registry Mumber 7481-20-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,8 and 1 respectively; the second part has 2 digits, 2 and 0 respectively. Calculate Digit Verification of CAS Registry Number 7481-20: (6*7)+(5*4)+(4*8)+(3*1)+(2*2)+(1*0)=101 101 % 10 = 1 So 7481-20-1 is a valid CAS Registry Number.
