Check Digit Verification of cas no
The CAS Registry Mumber 111480-84-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,8 and 0 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 111480-84:
(8*1)+(7*1)+(6*1)+(5*4)+(4*8)+(3*0)+(2*8)+(1*4)=93
93 % 10 = 3
So 111480-84-3 is a valid CAS Registry Number.

NaClO2-mediated preparation of pyridine-2-sulfonyl chlorides and synthesis of chiral sulfonamides
Xu, Dong,Yang, Shiyi,Gao, Aijun,Yang, Zhanhui
, p. 463 - 473 (2020/07/03)
A simple method to prepare azaarenesulfonyl chlorides by NaClO2-mediated oxidative chlorination of azaarenethiols have been developed, with water as the solvent. Easy purification by simple extraction and concentration gives the products in good yields. The azaarenesulfonyl chlorides readily undergo condensation with chiral amines to afford chiral sulfonamides.
