Check Digit Verification of cas no

The CAS Registry Mumber 139534-85-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,5,3 and 4 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 139534-85:
(8*1)+(7*3)+(6*9)+(5*5)+(4*3)+(3*4)+(2*8)+(1*5)=153
153 % 10 = 3
So 139534-85-3 is a valid CAS Registry Number.

Glycosylation with sialic acid at HO-3 of three different O-protected D-galactosides in acetonitrile/dichloromethane at low temperature

Birberg,Lonn

, p. 7457 - 7458 (2007/10/02)

Three different O-protected D-galactosides have been compared as acceptors in α-sialoside synthesis using glycosyl donor 1, methylsulfenyl triflate as promoter, and acetonitrile/dichloromethane as solvent at -70°C. The 6-O-benzylated acceptor 2 was the most efficient, the α(2-3)sialoside 5 was obtained in 39% isolated yield.
