Check Digit Verification of cas no

The CAS Registry Mumber 1286741-82-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,6,7,4 and 1 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1286741-82:
(9*1)+(8*2)+(7*8)+(6*6)+(5*7)+(4*4)+(3*1)+(2*8)+(1*2)=189
189 % 10 = 9
So 1286741-82-9 is a valid CAS Registry Number.

Iron-catalyzed stereospecific olefin synthesis by direct coupling of alcohols and alkenes with alcohols

Liu, Zhong-Quan,Zhang, Yuexia,Zhao, Lixing,Li, Zejiang,Wang, Jiantao,Li, Huajie,Wu, Long-Min

supporting information; experimental part, p. 2208 - 2211 (2011/06/20)

Chemical equations presented. An efficient Fe(III)-catalyzed direct coupling of alkenes with alcohols and cross-coupling of alcohols with alcohols to give the corresponding substituted (E)-alkenes stereospecifically is demonstrated. Additionally, this reaction could be scaled up. The kinetic isotope effect (KIE) experiments indicated a typical secondary isotope effect in this process. Although benzylic alcohols were effective substrates, mild conditions, atom efficiency, environmental soundness, and stereospecificity are features that make this procedure very attractive.
