128981-75-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128981-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,9,8 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 128981-75:
(8*1)+(7*2)+(6*8)+(5*9)+(4*8)+(3*1)+(2*7)+(1*5)=169
169 % 10 = 9
So 128981-75-9 is a valid CAS Registry Number.

The cycloaddition reaction of α-oxo sulfines and 2-trimethylsilyloxy-1,3-butadienes
Rewinkel, J. B. M.,Zwanenburg, B.
, p. 190 - 196 (2007/10/02)
The cycloaddition reaction of α-oxo sulfines with 2-(trimethylsiloxy)-1,3-dienes, leading ultimately to thiacyclohexanone S-oxides (alternatively named as thianone S-oxides or perhydrothiapyranone S-oxides) is described. 1-Oxo-2-thioxo-indane S-oxide 2a,
