Check Digit Verification of cas no

The CAS Registry Mumber 18949-22-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,9,4 and 9 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18949-22:
(7*1)+(6*8)+(5*9)+(4*4)+(3*9)+(2*2)+(1*2)=149
149 % 10 = 9
So 18949-22-9 is a valid CAS Registry Number.

Reusable visible light photoredox catalysts; Catalyzed benzylic C(sp 3)-H functionalization/carbocyclization reactions

Xia, Jia-Dong,Deng, Guo-Bo,Zhou, Ming-Bo,Liu, Wei,Xie, Peng,Li, Jin-Heng

supporting information, p. 2707 - 2713,7 (2012/12/12)

The C(sp3)-H functionalization/carbocyclization reaction through the oxidative quenching of visible light photoredox catalysts is established for constructing functionalized 1H-indenes. The process is general for a wide range of benzylic C(sps

Inter- versus Intramolecular Friedel-Crafts Reaction of Phenyl-substituted Dichlorocyclopropanes

Anke, Lutz,Weyerstahl, Peter

, p. 613 - 619 (2007/10/02)

Friedel-Crafts reactions of the phenyl-substituted dichlorocyclopropanes 1-9 show different results.Thus, 1 (-> 10, 11), 3 (-> 12), 4(-> 13), 6 (-> 14), 8 (-> 15), and 9 (-> 16) yield indenes by the known intermolecular reaction with benzene.However, 2 (-

Electrochemical Reduction of Activated Carbon-Carbon Double Bonds. 1. Mechanism and Stereochemistry of the Reduction of Phenyl-Substituted Indenes

Farnia, Guiseppe,Marcuzzi, Franco,Melloni, Giovanni,Sandona, Giancarlo

, p. 6503 - 6512 (2007/10/02)

The reduction at a Hg electrode in DMF of some phenyl-substituted indenes was carried out, with the aim of finding out possible relationships between stereochemistry and mechanism of the reaction.The two-electron two-proton reduction occured exclusively a
