121947-75-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 121947-75-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,9,4 and 7 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 121947-75:
(8*1)+(7*2)+(6*1)+(5*9)+(4*4)+(3*7)+(2*7)+(1*5)=129
129 % 10 = 9
So 121947-75-9 is a valid CAS Registry Number.

THE EFFECT OF REPLACING A 3-O-ACETYL GROUP BY A 3-O-BENZY; GROUP IN A METHYL 4-O-TRITYL-β-D-XYLOPYRANOSIDE DERIVATIVE ON THE EFFICIENCY OF 1,2-trans-GLYCOSYLATION WITH A D-XYLOSE 1,2-O-(1-CYANOETHYLIDENE) DERIVATIVE

Nifantev, Nikolay E.,Backinowsky, Leon V.,Kochetkov, Nikolay K.

, p. 13 - 20 (2007/10/02)

Replacement of AcO-3 in methyl 2,3-di-O-acetyl-4-O-trityl-β-D-xylopyranoside with a benzyl group greatly increases the 1,2-trans-stereoselectivity of glycosylation with D-xylopyranose 1,2-O-(1-Cyanoethylidene) derivative.Anomerisation of methyl 2-O-benzyl-β-D-xylopyranoside derivatives occured under the action of triphenylmethylium perchlorate.
