42797-33-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42797-33-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,7,9 and 7 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 42797-33:
(7*4)+(6*2)+(5*7)+(4*9)+(3*7)+(2*3)+(1*3)=141
141 % 10 = 1
So 42797-33-1 is a valid CAS Registry Number.

Synthesis of cyclic polysulfides: Controlled ring-expansion polymerization of cyclic tetrathioester with thiirane
Kudo, Hiroto,Takeshi, Yuki
, p. 857 - 866 (2014/03/21)
We synthesized cyclic tetrathioesters containing thioester moieties at the o-position (o-CTE) and m-position (m-CTE) of an aromatic skeleton. The reaction of phenoxy propylenesulfide (PPS) with o-CTE and m-CTE was examined using tetrabutylammonium chlorid
