109536-51-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 109536-51-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,5,3 and 6 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 109536-51:
(8*1)+(7*0)+(6*9)+(5*5)+(4*3)+(3*6)+(2*5)+(1*1)=128
128 % 10 = 8
So 109536-51-8 is a valid CAS Registry Number.

Yb(OTf)3·H2O: A novel reagent for the chemoselective hydrolysis of isopropylidene acetals

Yadav,Reddy, B. V. Subba,Reddy, K. Srinivasa

, p. 430 - 431 (2001)

A facile chemoselective hydrolysis of terminal isopropylidene acetals has been achieved using a catalytic amount of Yb(OTf)3·H2O in acetonitrile at ambient temperature.

Sulfuric acid immobilized on silica: an efficient reusable catalyst for selective hydrolysis of the terminal O-isopropylidene group of sugar derivatives

Rajput, Vishal Kumar,Roy, Bimalendu,Mukhopadhyay, Balaram

, p. 6987 - 6991 (2006)

Sulfuric acid immobilized on silica proved to be an efficient catalyst for selective hydrolysis of the terminal O-isopropylidene group of sugar derivatives. The method is very simple and economic for large-scale synthesis in which the catalyst is recovered and reused for several runs. Reactions with di-O-isopropylidene derivatives of d-glucose, d-mannose, d-fructose and l-sorbose led to the formation of the corresponding mono-O-isopropylidene derivatives in good to excellent yields.

Synthesis of imidazo[2,1-b]thiazoles linked to an unprotected carbohydrate moiety

Barradas, Jose Sebastian,Errea, Maria Ines,D'Accorso, Norma Beatriz

scheme or table, p. 79 - 86 (2012/07/28)

Two series of imidazo[2,1-b]thiazoles substituted on C-3 or C-5 with an unprotected carbohydrate moiety were synthesized. Different protective groups for position 3 of the carbohydrate moiety were tested (acetyl, tert-butyldimethylsilyl (TBDMS), and p-met
