Check Digit Verification of cas no

The CAS Registry Mumber 82053-18-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,0,5 and 3 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 82053-18:
(7*8)+(6*2)+(5*0)+(4*5)+(3*3)+(2*1)+(1*8)=107
107 % 10 = 7
So 82053-18-7 is a valid CAS Registry Number.

Efficient Br?nsted acid catalyzed Hosomi-Sakurai reaction of acetals

Kampen, Daniela,List, Benjamin

, p. 2589 - 2592 (2006)

Acetals react with allyltrimethylsilane in the presence of a catalytic amount of sulfonic acids to give the corresponding homoallylic ethers in high yields. The scope of the reaction is broad and both aromatic as well as aliphatic acetals can readily be u

Catalytic Use of Elemental Gallium for Carbon-Carbon Bond Formation

Qin, Bo,Schneider, Uwe

supporting information, p. 13119 - 13122 (2016/10/25)

The first catalytic use of Ga(0) in organic synthesis has been developed by using a Ag(I) cocatalyst, crownether ligation, and ultrasonic activation. Ga(I)-catalyzed C-C bond formations between allyl or allenyl boronic esters and acetals, ketals, or aminals have proceeded in high yields with essentially complete regio- and chemoselectivity. NMR spectroscopic analyses have revealed novel transient Ga(I) catalytic species, formed in situ through partial oxidation of Ga(0) and B-Ga transmetalation, respectively. The possibility of asymmetric Ga(I) catalysis has been demonstrated.

Mesoporous aluminosilicate-catalyzed allylation of carbonyl compounds and acetals

Ito, Suguru,Hayashi, Akira,Komai, Hirotomo,Yamaguchi, Hitoshi,Kubota, Yoshihiro,Asami, Masatoshi

experimental part, p. 2081 - 2089 (2011/04/19)

A mesoporous aluminosilicate (Al-MCM-41) was found to be an effective heterogeneous catalyst for the reaction of both carbonyl compounds and acetals with allylsilanes to afford the corresponding homoallyl silyl ethers and homoallyl alkyl ethers, respectively. Both the mesoporous structure and the presence of aluminum moiety were indispensable for the high catalytic activity of Al-MCM-41. Moreover, Al-MCM-41 could catalyze the reaction of acetals chemoselectively in the presence of the corresponding carbonyl compounds. The solid acid catalyst Al-MCM-41 could be recovered easily by filtration and could be reused three times without a significant loss of catalytic activity.
