2-((Z)-2-Bromo-2-carboxy-vinyl)-benzoic acid is a complex organic compound with the molecular formula C9H5BrO4. It is characterized by a benzoic acid structure, where one of the hydrogen atoms on the benzene ring is replaced by a (Z)-2-bromo-2-carboxy-vinyl group. This group consists of a vinyl (C=C) double bond with a bromine atom attached to one carbon and a carboxyl group (-COOH) attached to the other carbon. The compound exhibits a Z configuration, indicating the geometric arrangement of the double bond, with the bromine and carboxyl groups on the same side of the double bond. This chemical is known for its potential applications in the synthesis of pharmaceuticals and other organic compounds, particularly those involving halogenated aromatic systems.

Check Digit Verification of cas no

The CAS Registry Mumber 86905-49-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,9,0 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 86905-49:
(7*8)+(6*6)+(5*9)+(4*0)+(3*5)+(2*4)+(1*9)=169
169 % 10 = 9
So 86905-49-9 is a valid CAS Registry Number.
