54985-37-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54985-37-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,9,8 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 54985-37:
(7*5)+(6*4)+(5*9)+(4*8)+(3*5)+(2*3)+(1*7)=164
164 % 10 = 4
So 54985-37-4 is a valid CAS Registry Number.

Stereoselective Traceless Borylation–Allenation of Propargylic Epoxides: Dual Role of the Copper Catalyst

Jarava-Barrera, Carlos,Parra, Alejandro,Amenós, Laura,Arroyo, Ana,Tortosa, Mariola

, p. 17478 - 17481 (2017/11/30)

Chiral α-allenols are prepared with high diastereocontrol through an unprecedented and spontaneous β-oxygen elimination of an α-epoxy vinyl boronate. Stochiometric experiments and DFT calculations support a dual role of the copper catalyst, which orchestrates the hydroboration and the syn-elimination step.

On the Transmetallation of (E)-1-Phenyl-3-(tributylstannyl)propene and 3-Phenyl-3-(tributylstannyl)propene with BuSnCl3

Miyake, Hideyoshi,Yamamura, Kimiaki

, p. 1473 - 1474 (2007/10/02)

Transmetallation of (E)-1-phenyl-3-(tributylstannyl)propene and 3-phenyl-3-(tributylstannyl)propene with BuSnCl3, and the isomerization of the transmetallated product are described.The application of the reactions to stereoselective (Z)-3-phenyl-2-propenylation and threo-1-phenyl-2-propenylation of aldehydes is also described.
