Toluene-4-sulfonic acid norborn-2-ene-7anti-yl ester is a complex organic compound with the chemical formula C₁₃H₁₈O₃S. It is derived from toluene-4-sulfonic acid, a strong acid used in various organic synthesis reactions, and norborn-2-ene-7anti-yl, a bicyclic hydrocarbon structure. This ester is formed through the reaction between the carboxylic acid group of toluene-4-sulfonic acid and the hydroxyl group of norborn-2-ene-7anti-yl, resulting in the formation of an ester linkage. The compound is characterized by its unique structure, which includes a toluene ring, a sulfonic acid group, and a norbornane core. It is typically used as an intermediate in the synthesis of various pharmaceuticals and other organic compounds due to its reactive functional groups and unique stereochemistry.

Check Digit Verification of cas no

The CAS Registry Mumber 5371-40-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,3,7 and 1 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 5371-40:
(6*5)+(5*3)+(4*7)+(3*1)+(2*4)+(1*0)=84
84 % 10 = 4
So 5371-40-4 is a valid CAS Registry Number.
