The CAS Registry Mumber 13407-60-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,0 and 7 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13407-60:
(7*1)+(6*3)+(5*4)+(4*0)+(3*7)+(2*6)+(1*0)=78
78 % 10 = 8
So 13407-60-8 is a valid CAS Registry Number.

Reversed imidazole nucleosides. Alternative pathways of synthesis

Walczak,Suwinski

, p. 1028 - 1036 (2007/10/03)

The reversed imidazole nucleosides were obtained on three independent routes: a) by the nucleophilic substitution of terminal tosylate group in sugar derivatives with imidazole-1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) salts, b) from monosugar derivatives with unprotected terminal hydroxy group and substituted imidazoles, under the Mitsunobu reactions conditions, c) by the reaction of monosugars possessing terminal primary amino group with 1,4-dinitroimidazoles. Limitations of these routes are discussed.
