193481-15-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 193481-15-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,9,3,4,8 and 1 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 193481-15:
(8*1)+(7*9)+(6*3)+(5*4)+(4*8)+(3*1)+(2*1)+(1*5)=151
151 % 10 = 1
So 193481-15-1 is a valid CAS Registry Number.

Synthesis of Penta-2,4-dien-1-imines and 1,2-Dihydropyridines by Rhodium-Catalyzed Reaction of N-Sulfonyl-1,2,3-triazoles with 2-(Siloxy)furans

Funakoshi, Yuuta,Miura, Tomoya,Murakami, Masahiro

supporting information, p. 6284 - 6287 (2016/12/23)

A rhodium(II)-catalyzed reaction of N-sulfonyl-1,2,3-triazoles with 2-(siloxy)furans is reported. Either open-chain penta-2,4-dien-1-imines or cyclic 1,2-dihydropyridines are selectively obtained depending on the ligand on rhodium(II).

2-Siloxy-4-furanyl anion: Remarkable solvent effect on its nucleophilicity

Xin,Zheng,Stewart

, p. 1324 - 1326 (2007/10/03)

A significant solvent effect was observed for 2-triisopropylsiloxyl-4-furanyllithium complex (II) in nucleophilic addition of ketones. THF was found to be the best solvent in terms of yields and diastereoselectivity.
