Check Digit Verification of cas no

The CAS Registry Mumber 14795-21-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,7,9 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 14795-21:
(7*1)+(6*4)+(5*7)+(4*9)+(3*5)+(2*2)+(1*1)=122
122 % 10 = 2
So 14795-21-2 is a valid CAS Registry Number.

Protecting-group-free synthesis of glycosyl 1-phosphates

Edgar, Landon John G.,Dasgupta, Somnath,Nitz, Mark

supporting information; experimental part, p. 4226 - 4229 (2012/09/22)

Glycosyl 1-phosphates enriched in the α-anomer are obtained without the use of protecting groups in two steps starting from the free hemiacetal. Condensation of free hemiacetals with toluenesulfonylhydrazide yields a range of glycosylsulfonohydrazide donors which can be oxidized using cupric chloride in the presence of phosphoric acid and the coordinating additive 2-methyl-2-oxazoline to give useful yields of the fully deprotected glycosyl 1-phosphates.
