74741-49-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 74741-49-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,4 and 1 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74741-49:
(7*7)+(6*4)+(5*7)+(4*4)+(3*1)+(2*4)+(1*9)=144
144 % 10 = 4
So 74741-49-4 is a valid CAS Registry Number.

Photo-induced glycosylation using a diaryldisulfide as an organo-Lewis photoacid catalyst

Iibuchi, Naoto,Eto, Takahiro,Aoyagi, Manabu,Kurinami, Reiji,Sakai, Hayato,Hasobe, Taku,Takahashi, Daisuke,Toshima, Kazunobu

supporting information, p. 851 - 855 (2020/02/15)

Photo-induced glycosylations of several acceptors with trichloroacetimidate donors using bis(2-naphthyl)disulfide as an organo-Lewis photoacid (LPA) catalyst proceeded effectively to give the corresponding glycosides in good to high yields. In addition, t

A visible light promoted O-glycosylation with glycosyl trichloroacetimidates using eosin Y as an organo photoacid

, (2020/03/06)

A photoacid catalyzed O-glycosylation of alcohols with glycosyl trichloroacetimidates in the presence of commercially available phenolic photoacids, fluorescein, 4′,5′-dibromo-fluorescein, and eosin Y under visible light irradiation by blue LEDs was devel

Photo-induced glycosylation using reusable organophotoacids

Iwata, Ryosuke,Uda, Kanjiro,Takahashi, Daisuke,Toshima, Kazunobu

supporting information, p. 10695 - 10698 (2014/09/30)

The glycosylation reactions of glycosyl trichloroacetimidates and several alcohols using an organophotoacid as an activator under photoirradiation proceeded smoothly to give the corresponding glycosides in high yields. The organophotoacid was recovered and reused without any loss of efficiency. This journal is the Partner Organisations 2014.
