The given chemical formula represents a quaternary ammonium salt, specifically a bromide salt of a trialkylamine. The compound consists of a central nitrogen atom (N) bonded to three alkyl groups: three ethyl groups (C2H5) and one butyl group (C4H9). The nitrogen atom carries a positive charge (1+), and the bromide ion (Br) carries a negative charge (1-), forming an ionic bond with the positively charged nitrogen. The overall structure is [(C4H9)(C2H5)3N]Br, indicating that the compound is a derivative of a trialkylamine with a bromide counterion.

Check Digit Verification of cas no

The CAS Registry Mumber 81591-85-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,9 and 1 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81591-85:
(7*8)+(6*1)+(5*5)+(4*9)+(3*1)+(2*8)+(1*5)=147
147 % 10 = 7
So 81591-85-7 is a valid CAS Registry Number.
