127945-87-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 127945-87-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,4 and 5 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 127945-87:
(8*1)+(7*2)+(6*7)+(5*9)+(4*4)+(3*5)+(2*8)+(1*7)=163
163 % 10 = 3
So 127945-87-3 is a valid CAS Registry Number.

, p. 2162 - 2173 (2007/10/02)
A series of acyclic and C-acyclic 7-deazapurine nucleosides have been synthesized and tested for antivirial activity.Reaction of the sodium salt of 2-amino-3,4-bis(aminocarbonyl)-5-(methylthio)pyrrole (6) with an appropriate electrophile gave pyrrole nucl
