264128-12-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 264128-12-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,4,1,2 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 264128-12:
(8*2)+(7*6)+(6*4)+(5*1)+(4*2)+(3*8)+(2*1)+(1*2)=123
123 % 10 = 3
So 264128-12-3 is a valid CAS Registry Number.

Novel carbohydrate scaffolds. Assembly of a uridine-mannose scaffold based on tunicamycin

Silva, Domingos J.,Sofia, Michael J.

, p. 855 - 858 (2007/10/03)

A disaccharide scaffold based on tunicamycin was synthesized from D- uridine and L-mannose. The key step in disaccharide assembly was a β- mannosylation performed using Crich's modification of the sulfoxide glycosylation method. The scaffold described contains two orthogonal derivatization sites and will be used in the search for novel biologically active compounds. (C) 2000 Elsevier Science Ltd.
