208644-68-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 208644-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,6,4 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 208644-68:
(8*2)+(7*0)+(6*8)+(5*6)+(4*4)+(3*4)+(2*6)+(1*8)=142
142 % 10 = 2
So 208644-68-2 is a valid CAS Registry Number.

HClO4-silica-catalysed regioselective opening of benzylidene acetals and its application towards regioselective HO-4 glycosylation of benzylidene acetals in one-pot

Dara, Saidulu,Saikam, Varma,Yadav, Mahipal,Singh, Parvinder Pal,Vishwakarma, Ram A.

supporting information, p. 93 - 96 (2014/05/20)

Here we report a high-yielding method for the regioselective reductive ring opening of 4,6-O-benzylidene acetals of hexapyranosides using inexpensive and robust HClO4-SiO2 as the acidic catalyst and triethylsilane as the hydride dono

4,6-O-[1-cyano-2-(2-iodophenyl)ethylidene] acetals. Improved second-generation acetals for the stereoselective formation of β-D-mannopyranosides and regioselective reductive radical fragmentation to β-D-rhamnopyranosides. Scope and limitations

Crich, David,Bowers, Albert A.

, p. 3452 - 3463 (2007/10/03)

The [1-cyano-2-(2-iodophenyl)]ethylidene group is introduced as an acetal-protecting group for carbohydrate thioglycoside donors. The group is easily introduced under mild conditions, over short reaction times, and in the presence of a wide variety of oth

Chemical synthesis of (4,6-Pyr)-Gal β1→4GlcNacβ1→3Fucβ1→OMe: A pyruvated trisaccharide related to the cell aggregation of the sponge Microciona prolifera

Deng, Shaojiang,Yu, Biao,Guo, Zhongwu,Hui, Yongzheng

, p. 439 - 452 (2007/10/03)

4,6-O-[(R)-1-carboxylethylidene] Galβ1→4GlcNAcβ1→3Fucβ1→OMe, a pyruvated trisaccharide unit involved in the aggregation factor of the marine sponge Microciona prolifera, was synthesized stereospecifically and unambiguously employing thioglycosides as glycosyl donors to construct glycosidic bonds.
