122128-13-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 122128-13-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,1,2 and 8 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 122128-13:
(8*1)+(7*2)+(6*2)+(5*1)+(4*2)+(3*8)+(2*1)+(1*3)=76
76 % 10 = 6
So 122128-13-6 is a valid CAS Registry Number.

A CONVENIENT STEREOSELECTIVE SYNTHESIS OF α-GLYCOSYL ESTERS

Barrett, Anthony G. M.,Bezuidenhoudt, Barend C. B.

, p. 209 - 212 (2007/10/02)

The anomeric hydroxyl group of 2,3,4,6-tetra-O-benzyl-D-glucopyranose was esterified by reaction of the derived anomeric alkoxide with 2-acylthio-3-nitropyridines at -78 deg C.The resultant esters were obtained with high anomeric diastereoselectivity (α:β
