Check Digit Verification of cas no

The CAS Registry Mumber 865086-04-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,6,5,0,8 and 6 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 865086-04:
(8*8)+(7*6)+(6*5)+(5*0)+(4*8)+(3*6)+(2*0)+(1*4)=190
190 % 10 = 0
So 865086-04-0 is a valid CAS Registry Number.

Formation of 4,5,6,7-tetrahydroisoindoles by palladium-catalyzed hydride reduction

Hou, Duen-Ren,Wang, Ming-Shiang,Chung, Ming-Wen,Hsieh, Yih-Dar,Tsai, Hui-Hsu Gavin

, p. 9231 - 9239 (2008/03/13)

(Chemical Equation Presented) Substituted 1,3-dihydro-2H-isoindoles (2, isoindolines) were prepared and subjected to palladium-catalyzed formate reduction. Alkyl isoindolines were reduced to 4,5,6,7-tetrahydro-2H-isoindoles (1). Only partial reduction was observed for 5-methoxyisoindoline, and 4-methoxy-, 5-carbomethoxy-, amino-, and amidoisoindolines were inert to the reaction. Halogen-substituted isoindolines were dehalogenated and reduced to 4,5,6,7-tetrahydro-2H-isoindoles. Isoindole 24 was also reduced to a mixture of an isoindoline and a 4,5,6,7-tetrahydro-2H-isoindole. In contrast, 2,3-dihydro-1H-indoles 21 underwent dehydrogenation to give thermodynamically stable indoles. Theoretical calculations show the significant difference in aromaticity between isoindoles and indoles, corresponding to the observed differences in reactivities. Tetrahydro-2H-isoindoles 1 were oxidized to 4,5,6,7-tetrahydroisoindole-1,3-diones in the presence of NBS and air.
