138904-55-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 138904-55-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,0 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138904-55:
(8*1)+(7*3)+(6*8)+(5*9)+(4*0)+(3*4)+(2*5)+(1*5)=149
149 % 10 = 9
So 138904-55-9 is a valid CAS Registry Number.

Synthesis of Furo[2,3-c]pyran-β-D-nucleosides by radical-cyclization and their conformational analysis by 500 MHz 1H-NMR spectroscopy

Xi,Agback,Sandstrom,Chattopadhyaya

, p. 9675 - 9690 (2007/10/02)

Free-radical, generated from the 3'-phenylseleno nucleosides as the radical precursors 2-5, was efficiently trapped intramolecularly by an olefin or alkyne function anchored from the 5'-end by an ether function to give various [3.4.0]-cis-fused furo[2,3-c
