Check Digit Verification of cas no

The CAS Registry Mumber 1335243-44-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,5,2,4 and 3 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1335243-44:
(9*1)+(8*3)+(7*3)+(6*5)+(5*2)+(4*4)+(3*3)+(2*4)+(1*4)=131
131 % 10 = 1
So 1335243-44-1 is a valid CAS Registry Number.

Chiral sulfoxide-olefin ligands: Tunable stereoselectivity in Rh-catalyzed asymmetric 1,4-additions

Chen, Guihua,Gui, Jiangyang,Cao, Peng,Liao, Jian

supporting information; experimental part, p. 3220 - 3224 (2012/06/01)

A class of chiral sulfoxide-olefins were designed and synthesized through concise routes. Their applications as ligands in Hayashi-Miyaura reaction were studied, which found that vinyl substituents of the ligands vary in stereocontrolling ability. Particularly, either isomer of adducts with excellent ees could be readily obtained through changing the position of the substituents of olefins as well as changing the configuration of the CC bond of the ligands. Meanwhile, the substrate scope of arylboronic acids and alkenes was clearly shown.
