1003-46-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1003-46-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,0 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1003-46:
(6*1)+(5*0)+(4*0)+(3*3)+(2*4)+(1*6)=29
29 % 10 = 9
So 1003-46-9 is a valid CAS Registry Number.

Radical [n + 1] annulations with sulfur dioxide
Tsimelzon, Anna,Braslau, Rebecca
, p. 10854 - 10859 (2007/10/03)
A new methodology for [n + 1] radical annulation using sulfur dioxide as a geminal radical acceptor/donor is presented. This methodology provides a novel route to the formation of five-, six-, and seven-membered cyclic sulfones utilizing a radical chain m
