91861-00-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91861-00-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,6 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91861-00:
(7*9)+(6*1)+(5*8)+(4*6)+(3*1)+(2*0)+(1*0)=136
136 % 10 = 6
So 91861-00-6 is a valid CAS Registry Number.

Stereospecific addition of formaldehyde dialkylhydrazones to sugar aldehydes. Synthesis of cyanohydrins and α-hydroxy aldehydes

Lassaletta, Jose M.,Fernandez, Rosario,Martin-Zamora, Eloisa,Pareja, Carmen

, p. 5787 - 5790 (2007/10/03)

Formaldehyde dialkylhydrazones smoothly add to sugar aldehydes without any need of promoter or catalyst. α-Hydroxy dialkylhydrazones, which are obtained in good yields and high stereoselectivities, have been successfully transformed in cyanohydrins by treatment with magnesium monoperoxyphtalate (MMPP) and in O-protected α-hydroxy aldehydes by ozonolysis or HCl mediated hydrolysis. No racemization was observed in the cleavage of the dialkylhydrazone group.

Iterative, Stereoselective Homologation of Chiral Polyalkoxy Aldehydes Employing 2-(Trimethylsilyl)thiazole as a Formyl Anion Equivalent. The Thiazole Route to Higher Carbohydrates

Dondoni, Alessandro,Fantin, Giancarlo,Fogagnolo, Marco,Medici, Alessandro,Pedrini, Paola

, p. 693 - 702 (2007/10/02)

A new approach to long-chain sugars is demonstrated by the stereoselective conversion of D-glyceraldehyde acetonide (2a), L-threose acetonide (2b), and dialdogalactopyranose diacetonide (2h) into higher homologues up to C9, C7, and C

A SYNTHESIS OF L-lyxo-L-altro-NONITOL, A NEW NONITOL

Brimacombe, John S.,Kabir, Abul K. M. S.

, p. 81 - 90 (2007/10/02)

Catalytic osmylation of (E)-6-O-benzyl-7,8-dideoxy-1,2:3,4-di-O-isopropylidene-α-D-glycero-D-galacto-non-7-enopyranose (15) proceeded with good stereoselectivity to give a mixture of 6-O-benzyl-1,2:3,4-di-O-isopropylidene-β-L-lyxo-D-galacto-nonopyranose (
