79439-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79439-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,4,3 and 9 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 79439-28:
(7*7)+(6*9)+(5*4)+(4*3)+(3*9)+(2*2)+(1*8)=174
174 % 10 = 4
So 79439-28-4 is a valid CAS Registry Number.

INTERVENTION OF SULFINYL SULFONE IN THE OXIDATION PATHWAY OF THIOSULFONIC S-ESTER TO α-DISULFONE
Oae, Shigeru,Takata, Toshikazu
, p. 845 - 848 (1981)
Sulfinyl sulfone was confirmed as a stable intermediate in direct NMR study on the oxidation of thiosulfonic S-ester with MCPBA in CDCl3, by comparing the chemical shifts with those of the authentic sample prepared by condensation method.
