55750-51-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 55750-51-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,7,5 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 55750-51:
(7*5)+(6*5)+(5*7)+(4*5)+(3*0)+(2*5)+(1*1)=131
131 % 10 = 1
So 55750-51-1 is a valid CAS Registry Number.

Indium-Catalyzed Amide Allylation of N-Carbonyl Imides: Formation of Azaspiro-γ-lactones via Ring Opening-Reclosure

Sengoku, Tetsuya,Murata, Yusuke,Aso, Yuwa,Kawakami, Ai,Inuzuka, Toshiyasu,Sakamoto, Masami,Takahashi, Masaki,Yoda, Hidemi

supporting information, p. 5846 - 5849 (2015/12/11)

A novel and facile synthesis of azaspiro-γ-lactones with a methylene-lactam framework from N-carbonyl imides is described. Mechanistic investigations provide evidence for a two-step reaction process involving ZnCl2-promoted addition of β-amido allylindium species followed by an unexpectedly molecular-sieves-mediated ring opening-reclosure concomitantly with the loss of an N-carbonyl unit.
