723-51-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 723-51-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,2 and 3 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 723-51:
(5*7)+(4*2)+(3*3)+(2*5)+(1*1)=63
63 % 10 = 3
So 723-51-3 is a valid CAS Registry Number.

A convenient preparation of heteroaryl sulfonamides and sulfonyl fluorides from heteroaryl thiols

Wright, Stephen W.,Hallstrom, Kelly N.

, p. 1080 - 1084 (2006)

Heteroaromatic thiols may be oxidized to the sulfonyl chloride at low temperature (-25 °C) by using 3.3 equiv of aqueous sodium hypochlorite. The reaction is rapid, avoids the use of chlorine gas, and succeeds with substrates that have previously been found to afford little or none of the sulfonamide product with other procedures. The method allows the preparation of the sulfonyl fluorides, which are stable enough to be purified and stored, making them potentially useful monomers in parallel chemistry efforts.

Metal-Free Intermolecular Aminoarylation of Alkynes

Rabet, Pauline T. G.,Boyd, Scott,Greaney, Michael F.

, p. 4183 - 4186 (2017)

A metal-free aminoarylation of internal alkynes is described, yielding tetrasubstituted enaminoates. The transformation proceeds in good to excellent yields through a tandem conjugate addition/Smiles rearrangement involving aryl and heteroaryl sulfonamide
