Check Digit Verification of cas no

The CAS Registry Mumber 1201909-57-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,1,9,0 and 9 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1201909-57:
(9*1)+(8*2)+(7*0)+(6*1)+(5*9)+(4*0)+(3*9)+(2*5)+(1*7)=120
120 % 10 = 0
So 1201909-57-0 is a valid CAS Registry Number.

Reactions of vinylidenecyclopropanes with diphenyl diselenide in the presence of AIBN and thermally-induced further transformations

Yuan, Wei,Wei, Yin,Shi, Min,Li, Yuxue

, p. 1280 - 1285 (2012/03/26)

In conclusion, we have developed a novel tandem reaction of VDCPs 1 with PhSeSePh to give the corresponding bicyclo[3.1.0]hexane derivatives 4 in good yields in the presence of AIBN, which could undergo a thermal-induced radical 1,4-hydrogen shift through

Halogenation reagents initiating ring opening of vinylidenecyclopropanes: Easy access to halogenated tetrahydropyrans

Yuan, Wei,Shi, Min

, p. 995 - 999 (2011/06/17)

A novel synthetic protocol that uses halogenation reagents (NBS, NIS and selectfluor) to initiate intramolecular ring-opening reactions of diarylvinylidenecyclopropanes (VDCPs) connected to alcohol-bearing chains has been developed. The approach provides

Rhodium(I)-catalyzed intramolecular ene reaction of vinylidenecyclopropanes and alkenes for the formation of bicyclo[5.1.0]octylenes

Li, Wei,Yuan, Wei,Shi, Min,Hernandez, Erik,Li, Guigen

supporting information; experimental part, p. 64 - 67 (2010/03/03)

"Chemical Equation Presented" An efficient catalytic system for the intramolecular ene reaction of allene and alkene of diarylvinylidenecyclopropanes has been established. The reaction was achieved by using [RhCl(CO)2]2 as the cataly

Au/Ag-catalyzed intramolecular ring-opening of vinylidene-cyclopropanes (VDCPs): An easy access to functional tetrahydropyrans

Li, Wel,Yuan, Wel,Pindl, Surech,Shi, Min,Li, Guigen

supporting information; experimental part, p. 920 - 923 (2010/06/16)

Chemical Equation Presentation An intramolecular ring-opening of vinylidenecyclopropanes (VDCPs) tethered with alcohol chains has been established. A serles of transition metal catalysts and their combinations have been screened under mild conditions, and
