Check Digit Verification of cas no
The CAS Registry Mumber 113304-43-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,3,0 and 4 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 113304-43:
(8*1)+(7*1)+(6*3)+(5*3)+(4*0)+(3*4)+(2*4)+(1*3)=71
71 % 10 = 1
So 113304-43-1 is a valid CAS Registry Number.

NMR EVIDENCE FOR β-SULTONES AS INITIAL PRODUCTS IN REACTIONS OF OLEFINS WITH SULPHUR TRIOXIDE
Roberts, David W.,Jackson, Philip S.,Saul, Colin D.,Clemett, Colin J.
, p. 3383 - 3386 (2007/10/02)
NMR evidence is provided to show that low temperature sulphonation of simple olefins of all structural types involves initial formation of β-sultones, thus supporting the previously suggested concerted thermal ?2s + ?2s cycloaddition mechanism.
