Check Digit Verification of cas no

The CAS Registry Mumber 321679-30-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,1,6,7 and 9 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 321679-30:
(8*3)+(7*2)+(6*1)+(5*6)+(4*7)+(3*9)+(2*3)+(1*0)=135
135 % 10 = 5
So 321679-30-5 is a valid CAS Registry Number.

Stereoselective synthesis of epoxyalkyl glycoside precursors of glycosyl glycerol analogues from alkenyl glycosides of N-acetyl-D-glucosamine derivatives

Vega-Perez, Jose M.,Candela, Jose I.,Blanco, Eugenia,Iglesias-Guerra, Fernando

, p. 2471 - 2483 (2007/10/03)

The synthesis of epoxyalkyl glycoside derivatives of N-acetyl-D-glucosamine is described. Epoxidation of the corresponding alkenyl glycosides with m-CPBA took place with different stereoselectivity depending on the nature of the unsaturated system and the protecting groups on the sugar moiety. The configuration of the newly formed stereogenic centres has been confirmed unequivocally by chemical correlation.
