Check Digit Verification of cas no

The CAS Registry Mumber 2067-26-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,6 and 7 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2067-26:
(6*2)+(5*0)+(4*6)+(3*7)+(2*2)+(1*6)=67
67 % 10 = 7
So 2067-26-7 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.

Synthesis and reactions of [1-(trialkylsilyl)alkylidene]triphenylphosphoranes

Bestmann,Bomhard,Dostalek,Pichl,Riemer,Zimmermann

, p. 787 - 792 (2007/10/02)

Alkylidenetriphenylphosphoranes 1 react with trialkyl halosilanes 2 to afford silylated alkylidenephosphoranes 5, which can be converted to acylated alkylidenephosphoranes 8 and 10 by trimethylsilyl carboxylates 6 or carboxylic anhydrides 10. Bis(acylalkylidenephosphoranes) 13-15 are available from 5 and bis(trimethylsilyl) dicarboxylates 12 or cyclic or polymeric anhydrides 16, 17.
