Check Digit Verification of cas no

The CAS Registry Mumber 70509-09-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,0,5,0 and 9 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 70509-09:
(7*7)+(6*0)+(5*5)+(4*0)+(3*9)+(2*0)+(1*9)=110
110 % 10 = 0
So 70509-09-0 is a valid CAS Registry Number.

Synthesis of the Aminocyclitol Core of Jogyamycin via an Enantioselective Pd-Catalyzed Trimethylenemethane (TMM) Cycloaddition

Trost, Barry M.,Zhang, Lei,Lam, Tom M.

supporting information, p. 3938 - 3942 (2018/07/25)

The use of β-nitroenamines as a new class of acceptors in the enantioselective Pd-catalyzed trimethylenemethane cycloaddition afforded differentiated 1,2-dinitrogen bearing cyclopentanes with three contiguous stereocenters. The utility of these acceptors was demonstrated with the efficient construction of the core of jogyamycin and aminocyclopentitols. Further elaboration of the cycloadducts provided a concise synthetic approach toward joygamycin.

N-substituted imines by the copper-catalyzed N-imination of boronic acids and organostannanes with O-acyl ketoximes

Liu, Songbai,Yu, Ying,Liebeskind, Lanny S.

, p. 1947 - 1950 (2008/02/02)

Catalytic quantities of copper(I) or copper(II) sources catalyze the N-imination of boronic acids and organostannanes through reaction with oxime O-carboxylates under nonbasic conditions. This method tolerates various functional groups and takes place efficiently using aryl, heteroaryl, and alkenyl boronic acids and stannanes.
