Check Digit Verification of cas no
The CAS Registry Mumber 5435-31-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,4,3 and 5 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 5435-31:
(6*5)+(5*4)+(4*3)+(3*5)+(2*3)+(1*1)=84
84 % 10 = 4
So 5435-31-4 is a valid CAS Registry Number.

A general iodine-mediated synthesis of primary sulfonamides from thiols and aqueous ammonia
Feng, Jian-Bo,Wu, Xiao-Feng
supporting information, p. 6951 - 6954 (2016/07/30)
A general and efficient methodology for preparing primary sulfonamides has been developed. In the presence of iodine as the catalyst and TBHP (70% in water) as the oxidant, a wide range of primary sulfonamides were prepared from the corresponding thiols and aqueous ammonia in moderate to good yields.
