71204-44-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 71204-44-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,2,0 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 71204-44:
(7*7)+(6*1)+(5*2)+(4*0)+(3*4)+(2*4)+(1*4)=89
89 % 10 = 9
So 71204-44-9 is a valid CAS Registry Number.

A convenient method for the synthesis of cyclic trithiocarbonates on carbohydrate scaffolds

Saeed, Muhammad,Abbas, Muhammad,Abdel-Jalil, Raid J.,Zahid, Muhammad,Voelter, Wolfgang

, p. 315 - 317 (2003)

An efficient regio- and stereoselective method for the synthesis of cyclic trithiocarbonates on carbohydrate skeleton is described. A freshly prepared solution of sodium trithiocarbonate reacts with cis-oriented epoxytriflate pentoses 7-11 to yield the co

Regioselective and Stereoselective Oxirane Ring-Openings of 2,3-Anhydropentopyranosides with Some Methyl Group Donating Organometallic Reagents

Inghardt, Tord,Frejd, Torbjoern,Magnusson, Goeran

, p. 4542 - 4548 (2007/10/02)

By the proper choice of methyl group transferring reagents organometallic (Me4AlLi, Me4AlLi/MeLi (1:1), Me2CuLi, Me3Al, Me2Mg) it is possible to selectively introduce a methyl group into the 2- or 3-position via epoxide ring-opening of four easily availab

Synthesis of Sugar Nitrates by Nucloephilic Substitution

Afza, Nighat,Malik, Abdul,Latif, Farzana,Voelter, Wolfgang

, p. 1929 - 1934 (2007/10/02)

A rapid high-yielding synthesis of sugar mono- and dinitrates has been achieved via displacement of the trifluoromethylsulfonyloxy (triflate) by the nitrate group.This procedure is mild, convenient, and does not attack highly acid-labile groups.It also do
