139639-79-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139639-79-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,3 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 139639-79:
(8*1)+(7*3)+(6*9)+(5*6)+(4*3)+(3*9)+(2*7)+(1*9)=175
175 % 10 = 5
So 139639-79-5 is a valid CAS Registry Number.

Exceptionally high yield in glycosylation with sialic acid. Synthesis of a GM3 glycoside
Loenn, Hans,Stenvall, Kristina
, p. 115 - 116 (2007/10/02)
Exceptionally high yield was obtained in the glycosylation of HO-3 of lactose derivative 1 with xanthate 2 as sialosyl donor using methylsulfenyl triflate in acetonitrile/dichloromethane at -60°C. The yield of the sialosyl oligosaccharide was dependent on
