Check Digit Verification of cas no

The CAS Registry Mumber 61235-21-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,1,2,3 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 61235-21:
(7*6)+(6*1)+(5*2)+(4*3)+(3*5)+(2*2)+(1*1)=90
90 % 10 = 0
So 61235-21-0 is a valid CAS Registry Number.

Stereoselective radical Aryl migration reactions from sulfur to carbon

Bossart, Martin,Faessler, Roger,Schoenberger, Jan,Studer, Armido

, p. 2742 - 2757 (2007/10/03)

Stereoselective aryl migration reactions from sulfur in sulfonates and sulfonamides to C-centered radicals are reported. The 1,5-aryl migration from sulfur to differently substituted C-centered radicals could be performed with high yields and selectivities. Functionalized aryl groups could also be transferred by this new method. A model to explain the stereochemical outcome of the reaction is presented and some mechanistic aspects of this reaction are discussed. Aryl migration reactions from sulfur in sulfinates to carbon radicals were less efficient, and the corresponding migrations in aryl sulfoxides were not observed at all.
