124083-31-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 124083-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,0,8 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 124083-31:
(8*1)+(7*2)+(6*4)+(5*0)+(4*8)+(3*3)+(2*3)+(1*1)=94
94 % 10 = 4
So 124083-31-4 is a valid CAS Registry Number.

Cascade Copper-Catalyzed 1,2,3-Trifunctionalization of Terminal Allenes

Zhao, Wanxiang,Montgomery, John

, p. 9763 - 9766 (2016)

A cascade cyanation/diborylation of terminal allenes proceeds efficiently with copper catalysis using bis(pinacolato)diboron (B2Pin2) and N-cyano-N-phenyl-p-methylbenzenesulfonamide (NCTS) as reagents. Mechanistic studies suggest that the process proceeds through cyanoborylation of the substituted π-system of the allene followed by hydroboration of the remaining π-component. A wide array of product derivatives may be accessed through site-selective cross-couplings and N-bromosuccinimide-promoted heteroarylations as well as standard oxidative and reductive conversions of the initially obtained adducts.

Nitrodienic-like Reactivity of 2-Nitrofuran with Organometallic Reagents: One-step Synthesis of Alkylfuranones

, p. 7497 - 7508 (2007/10/02)

2-Nitrofuran reacts with Grignard, alkyllithium, dialkylcadmium and heterocuprate reagents affording mixtures of 5-alkyl- and 3-alkyl-2-furanones.
