51863-47-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 51863-47-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,8,6 and 3 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 51863-47:
(7*5)+(6*1)+(5*8)+(4*6)+(3*3)+(2*4)+(1*7)=129
129 % 10 = 9
So 51863-47-9 is a valid CAS Registry Number.

Oxidative Dephosphorylation of Benzylic Phosphonates with Dioxygen Generating Symmetrical trans-Stilbenes

Huang, Tianzeng,Chen, Tieqiao,Han, Li-Biao

, p. 2959 - 2965 (2018/03/09)

Under a dioxygen atmosphere, benzylphosphonates and related phosphoryl compounds can readily produce the corresponding trans-stilbenes in high yields with high selectivity upon treatment with bases. Various functional groups were tolerable under the reaction conditions.

Continuous-flow generation of diazoesters and their direct use in S-H and P-H insertion reactions: Synthesis of α-sulfanyl, α-sulfonyl, and α-phosphono carboxylates

Bartrum, Hannah E.,Blakemore, David C.,Moody, Christopher J.,Hayes, Christopher J.

, p. 2276 - 2282 (2013/04/10)

The synthesis of α-sulfanyl, α-sulfonyl, and α-phosphono carboxylates has been achieved using a two-step procedure involving the in-flow generation of diazoesters from sulfonylhydrazones, via Bamford-Stevens elimination, and then subsequent S-H, sulfinate

Polycondensed heterocycles. Part 11: Preparation and regioselective reductions of 5-phenyl-4H-pyrrolo[1,2-α][1]benzazepin-4-one

Garofalo, Antonio,Ragno, Gaetano,Campiani, Giuseppe,Brizzi, Antonella,Nacci, Vito

, p. 9351 - 9355 (2007/10/03)

The Wadsworth-Emmons olefination between 2-(1H-pyrrol-1-yl)benzaldehyde and methyl α-(diethylphosphonyl)phenyl-acetate leads exclusively to the cis-isomer of methyl 2-(1H-pyrrol-1-yl)-α-phenylcinnamate, which, after transformation into the corresponding a
