1450812-53-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1450812-53-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,5,0,8,1 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1450812-53:
(9*1)+(8*4)+(7*5)+(6*0)+(5*8)+(4*1)+(3*2)+(2*5)+(1*3)=139
139 % 10 = 9
So 1450812-53-9 is a valid CAS Registry Number.

Rh(III)-catalyzed oxidative coupling of 1,2-disubstituted arylhydrazines and olefins: A new strategy for 2,3-dihydro-1H-indazoles

Han, Sangil,Shin, Youngmi,Sharma, Satyasheel,Mishra, Neeraj Kumar,Park, Jihye,Kim, Mirim,Kim, Minyoung,Jang, Jinbong,Kim, In Su

supporting information, p. 2494 - 2497 (2014/05/20)

A rhodium(III)-catalyzed oxidative olefination of 1,2-disubstituted arylhydrazines with alkenes via sp2 C-H bond activation followed by an intramolecular aza-Michael reaction is described. This strategy allows the direct and efficient construct

Formation of enehydrazine intermediates through coupling of phenylhydrazines with vinyl halides: Entry into the Fischer indole synthesis

Zhan, Fuxu,Liang, Guangxin

supporting information, p. 1266 - 1269 (2013/03/13)

Cut to the chase: Direct formation of an enehydrazine, an intermediate in the classic Fischer indole synthesis, solves the regioselectivity problem associated with indolization. This approach not only achieves selective synthesis of indoles through proper selection of the vinyl halide, but also leads to quick construction of desoxyeseroline and esermethole, as well as the key structural motif in the Akuammiline alkaloid vincorine.
