N-propyl-2,1,3-benzothiadiazolium 2,4-dinitrobenzenesulphonate is a complex organic compound with the chemical formula C11H12N2O4S3. It is a derivative of benzothiadiazole, a heterocyclic compound with a benzene ring fused to a thiadiazole ring. This particular compound features a propyl group (a three-carbon alkyl chain) attached to the benzothiadiazole core, and a 2,4-dinitrobenzenesulphonate group as a counterion. The 2,4-dinitrobenzenesulphonate group consists of a benzene ring with two nitro groups at the 2 and 4 positions, and a sulfonate group attached to the para position. n-propyl-2,1,3-benzothiadiazolium 2,4-dinitrobenzenesulphonate is often used as a corrosion inhibitor, particularly in metalworking fluids, due to its ability to form a protective film on metal surfaces and prevent oxidation. It is also known for its antioxidant properties and can be used in various industrial applications to protect materials from degradation.

Check Digit Verification of cas no

The CAS Registry Mumber 7765-40-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,6 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7765-40:
(6*7)+(5*7)+(4*6)+(3*5)+(2*4)+(1*0)=124
124 % 10 = 4
So 7765-40-4 is a valid CAS Registry Number.
