134856-47-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 134856-47-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,8,5 and 6 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 134856-47:
(8*1)+(7*3)+(6*4)+(5*8)+(4*5)+(3*6)+(2*4)+(1*7)=146
146 % 10 = 6
So 134856-47-6 is a valid CAS Registry Number.

Construction of All-Carbon Quaternary Stereocenters by Scandium-Catalyzed Intramolecular C-H Alkylation of Imidazoles with 1,1-Disubstituted Alkenes

Lou, Shao-Jie,Mo, Zhenbo,Nishiura, Masayoshi,Hou, Zhaomin

, p. 1200 - 1205 (2020/02/04)

The exo-selective C-H cycloaddition of imidazoles to 1,1-disubstituted alkenes has been achieved for the first time by using half-sandwich scandium catalysts. A wide range of imidazole compounds bearing various 1,1-disubstituted aliphatic alkenes, styrenes, dienes, and enynes have been selectively converted in high yields to the corresponding bicyclic imidazole derivatives bearing β-all-carbon-substituted quaternary stereocenters. By using a chiral half-sandwich scandium catalyst, the asymmetric exo-selective cyclization has also been achieved with a high level of enantioselectivity.

A metal catalysed route to benzimidazoles containing a fused alicyclic ring

Anastasiou,Chaouk,Jackson

, p. 2499 - 2500 (2007/10/02)

Rhodium catalysed reactions of N-alkenyl-1,2-diaminobenzenes (1) with hydrogen and carbon monoxide give benzimidazoles containing a fused alicyclic ring (6,7) in excellent yields.
