Check Digit Verification of cas no

The CAS Registry Mumber 120591-36-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,5,9 and 1 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 120591-36:
(8*1)+(7*2)+(6*0)+(5*5)+(4*9)+(3*1)+(2*3)+(1*6)=98
98 % 10 = 8
So 120591-36-8 is a valid CAS Registry Number.

Hydrogenative Cyclopropanation and Hydrogenative Metathesis

Peil, Sebastian,Guthertz, Alexandre,Biberger, Tobias,Fürstner, Alois

, p. 8851 - 8856 (2019)

The unusual geminal hydrogenation of a propargyl alcohol derivative with [CpXRuCl] as the catalyst entails formation of pianostool ruthenium carbenes in the first place; these reactive intermediates can be intercepted with tethered alkenes to give either cyclopropanes or cyclic olefins as the result of a formal metathesis event. The course of the reaction is critically dependent on the substitution pattern of the alkene trap.

Unlocking a Diazirine Long-Lived Nuclear Singlet State via Photochemistry: NMR Detection and Lifetime of an Unstabilized Diazo-Compound

Procacci, Barbara,Roy, Soumya S.,Norcott, Philip,Turner, Norman,Duckett, Simon B.

, p. 16855 - 16864 (2018)

Diazirines are important for photoaffinity labeling, and their photoisomerization is relatively well-known. This work shows how hyperpolarized NMR spectroscopy can be used to characterize an unstable diazo-compound formed via photoisomerization of a 15N2-labeled silyl-ether-substituted diazirine. This diazirine is prepared in a nuclear spin singlet state via catalytic transfer of spin order from para-hydrogen. The active hyperpolarization catalyst is characterized to provide insight into the mechanism. The photochemical isomerization of the diazirine into the diazo-analogue allows the NMR invisible nuclear singlet state of the parent compound to be probed. The identity of the diazo-species is confirmed by trapping with N-phenyl maleimide via a cycloaddition reaction to afford bicyclic pyrazolines that also show singlet state character. The presence of singlet states in the diazirine and the diazo-compound is validated by comparison of experimental nutation behavior with theoretical simulation. The magnetic state lifetime of the diazo-compound is determined as 12 ± 1 s in CD3OD solution at room temperature, whereas its chemical lifetime is measured as 100 ± 5 s by related hyperpolarized NMR studies. Indirect evidence for the generation of the photoproduct para-N2 is presented.

Alkene Ozonolysis in the Presence of Diazo Functionality: Accessing an Intermediate for Squalestatin Synthesis

Almohseni, Hasanain A. A.,Arif, Tanzeel,Fegheh-Hassanpour, Younes,Hodgson, David M.

, p. 4231 - 4238 (2019)

Studies on both the propensity for intramolecular cycloaddition between diazo and alkene functionality, and the tolerance of α-substituted α-diazoesters towards ozone in the presence of an alkene, led to chemoselective alkene ozonolysis of an ?-unsaturated-α-diazoester to give a key racemic diazoketone for the synthesis of 6,7-dideoxysqualestatin H5.
