133470-97-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 133470-97-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,4,7 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133470-97:
(8*1)+(7*3)+(6*3)+(5*4)+(4*7)+(3*0)+(2*9)+(1*7)=120
120 % 10 = 0
So 133470-97-0 is a valid CAS Registry Number.

5-Amino-3-β-D-ribofuranosylpyrazolo[3,4-e][1,3]oxazin-7-one has been synthesized via cyclization of the appropriately protected pyrazofurin derivatives and subsequent transformations of the hetorocyclic moiety. This guanosine analogue was marginally cytot
