Toluene-4-sulfonic acid-(N-chloro-o-toluidide) is a chemical compound that can be described as a derivative of toluene-4-sulfonic acid, where the para-position (4-position) of the benzene ring is substituted with a sulfonic acid group. The N-chloro-o-toluidide part of the name indicates that an o-toluidine molecule (an o-methylaniline) has been chlorinated at the nitrogen atom. toluene-4-sulfonic acid-(N-chloro-o-toluidide) is likely used in chemical synthesis, particularly in reactions where a chlorinated amine group is required, such as in the preparation of certain dyes, pharmaceuticals, or other organic compounds. The specific properties and applications of toluene-4-sulfonic acid-(N-chloro-o-toluidide) would depend on the context in which it is used, but it is generally known for its reactivity due to the presence of the chlorinated amine group and the acidic sulfonic acid group.

Check Digit Verification of cas no

The CAS Registry Mumber 2903-39-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,0 and 3 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2903-39:
(6*2)+(5*9)+(4*0)+(3*3)+(2*3)+(1*9)=81
81 % 10 = 1
So 2903-39-1 is a valid CAS Registry Number.
