Check Digit Verification of cas no

The CAS Registry Mumber 81347-74-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,4 and 7 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 81347-74:
(7*8)+(6*1)+(5*3)+(4*4)+(3*7)+(2*7)+(1*4)=132
132 % 10 = 2
So 81347-74-2 is a valid CAS Registry Number.

A practical method for the synthesis of N-(2-carbonylaryl) benzenesulfonamides via an iron-catalyzed electrophilic amination of sodium sulfinates with anthranils is described. This redox-neutral transformation has high atom efficiency and is achieved under simple and mild reaction conditions. A wide range of anthranils and sodium sulfinates were compatible in this transformation. Moreover, the synthetic potential of this methodology was further demonstrated by the synthesis of various useful N-heterocycles and derivatives.
