Check Digit Verification of cas no

The CAS Registry Mumber 1450-09-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,5 and 0 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1450-09:
(6*1)+(5*4)+(4*5)+(3*0)+(2*0)+(1*9)=55
55 % 10 = 5
So 1450-09-5 is a valid CAS Registry Number.

Transition-Metal-Free Reductive Deoxygenative Olefination with CO2

Zhu, Dao-Yong,Li, Wen-Duo,Yang, Ce,Chen, Jie,Xia, Ji-Bao

supporting information, p. 3282 - 3285 (2018/06/11)

A new transition-metal-free reductive deoxygenative olefination of phosphorus ylides with CO2, an abundant and sustainable C1 chemical feedstock, is described. This catalytic CO2 fixation afforded β-unsubstituted acrylates and vinyl ketones in good yields with broad scope and good functional group tolerance under mild reaction conditions. Cost-effective and easily handled polymethylhydrosiloxane was used as a reductant. Bis(silyl)acetal was proved to be the key intermediate in this reductive functionalization of CO2.

Aitken, R. Alan,Cadogan, J. I. G.,Gosney, Ian

, p. 281 - 286 (2007/10/02)

Oxidative cleavage of a range of ylides 4 with R1 and/or R2 being aromatic groups, using KMnO4 in a two-phase system, affords unsymmetrical benzils and 1-arylpropane-1,2-diones 5 in moderate to good yield, and the ylide formation and oxidation can be combined in a convenient one-pot method.Key words: Phosphorus ylides, oxidation, 1,2-diketones, benzils, permanganate, oxoalkylidenetriphenylphosphoranes.
