159389-47-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 159389-47-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,3,8 and 9 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 159389-47:
(8*1)+(7*5)+(6*9)+(5*3)+(4*8)+(3*9)+(2*4)+(1*7)=186
186 % 10 = 6
So 159389-47-6 is a valid CAS Registry Number.

Access to Cyclopropyl-Fused Azacycles via a Palladium-Catalyzed Direct Alkenylation Strategy

Ladd, Carolyn L.,Charette, André B.

, p. 6046 - 6049 (2016)

Palladium-catalyzed direct alkenylation of cyclopropyl C-H bonds proceeds in high efficiency. This transformation provides access to novel cyclopropyl-fused azacycles. Ligand studies suggest that bisphosphine monoxide analogues of dppf and rac-BINAP are t

A general strategy for visible-light decaging based on the quinone: Cis -alkenyl lock

Walton, David P.,Dougherty, Dennis A.

supporting information, p. 4965 - 4968 (2019/05/21)

Combining the fast thermal cyclization of o-coumaric acid derivatives with the intramolecular photoreduction of quinones gives new visible-light photoremovable protecting groups absorbing well above 450 nm.

CuI/amino acid-catalyzed coupling and cyclization of β-bromo-α, β-unsaturated amides with terminal alkynes leading to (3Z)-3- alkylidenepyrrol-1-ones

Son, Jong Ik,Cho, Chan Sik,Choi, Heung-Jin

, p. 380 - 386 (2013/07/26)

β-Bromo-α,β-unsaturated amides are coupled and cyclized with terminal alkynes in DMF at 110 °C in the presence of a catalytic amount of CuI and amino acid along with a base to give the corresponding (3Z)-3-alkylidenepyrrol-1-ones in moderate to good yield
