Check Digit Verification of cas no
The CAS Registry Mumber 159087-46-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,0,8 and 7 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 159087-46:
(8*1)+(7*5)+(6*9)+(5*0)+(4*8)+(3*7)+(2*4)+(1*6)=164
164 % 10 = 4
So 159087-46-4 is a valid CAS Registry Number.

Stereocontrolled synthesis of 1,2- and 1,3-diamine building blocks from aziridine aldehyde dimers
Liew, Sean K.,He, Zhi,St. Denis, Jeffrey D.,Yudin, Andrei K.
, p. 11637 - 11645 (2013)
Vicinal aziridine-containing diamines have been obtained with high syn-stereoselectivity from readily available aziridine aldehyde dimers in the Petasis borono-Mannich reaction. Subsequent solvent- and/or nucleophile- dependent ring-opening of the aziridine ring yields functionalized 1,2- and 1,3-diamines with high regioselectivity. The ring opening is also influenced by the substitution at the C3 position of the aziridine. A mechanistic rationale for the highly syn-selective three-component reaction is proposed.
Monosubstituted 3,3-Difluorocyclopropenes as Bench-Stable Reagents: Scope and Limitations

A general approach to gem-difluorocyclopropenes synthesis based on the reaction of alkynes with Ruppert-Prakash reagent is reported. The proposed method is evaluated for the synthesis of a wide difluorocyclopropenes scope based on their bench lifespan and hydrolytic stability. The tolerance of the method for common functional groups was shown. Previously unavailable difluorocyclopropenes substituted with aliphatic were prepared using the proposed procedure. The retain of stability was proven by the multigram scale synthesis and further storage in the temperature interval ?78 to ?4 °C over a year. This makes them attractive building blocks and intermediates for organic synthesis. The reasons for dropping stability were defined. The relations between the structure of the substituents and the stability of the difluorocyclopropene ring were determined and discussed.
