15954-46-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 15954-46-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,9,5 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 15954-46:
(7*1)+(6*5)+(5*9)+(4*5)+(3*4)+(2*4)+(1*6)=128
128 % 10 = 8
So 15954-46-8 is a valid CAS Registry Number.

Dual Nickel/Photoredox-Catalyzed Deaminative Cross-Coupling of Sterically Hindered Primary Amines

Dorsheimer, Julia R.,Ashley, Melissa A.,Rovis, Tomislav

, p. 19294 - 19299 (2021/11/23)

We report a method to activate α-3° amines for deaminative arylation via condensation with an electron-rich aldehyde and merge this reactivity with nickel metallaphotoredox to generate benzylic quaternary centers, a common motif in pharmaceuticals and natural products. The reaction is accelerated by added ammonium salts. Evidence is provided in support of two roles for the additive: inhibition of nickel black formation and acceleration of the overall reaction rate. We demonstrate a robust scope of amine and haloarene coupling partners and show an expedited synthesis of ALK2 inhibitors.

Conformational Dependence of 13C SCS in 1-Methyl-1-phenylcyclohexanes

Cook, Michael J.,Nasri, Khalida A.

, p. 644 - 647 (2007/10/02)

13C chemical shift data are reported for a series of para-substituted 1-methyl-1-phenylcyclohexanes at 22 and -100 deg C.The magnitudes of the SCS at alkyl and cycloalkyl carbon positions are discussed.The SCS at C-methyl and C-4 are significantly differe
