339091-18-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 339091-18-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,9,0,9 and 1 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 339091-18:
(8*3)+(7*3)+(6*9)+(5*0)+(4*9)+(3*1)+(2*1)+(1*8)=148
148 % 10 = 8
So 339091-18-8 is a valid CAS Registry Number.

Total synthesis of 2'-O-methyl-β-L-arabinosyluridine and reassignment the nucleoside from penicillium sp. as 2'-O-methyl-β-L-uridine

, p. 68 - 72 (2020)

In order to validate the structure of a rarely reported naturally occurring nucleoside isolated from the broth of Penicillium sp. (NO. 64), practical syntheses of 2′-O-methyl-β-L-arabinosyluridine, 2′-O-methyl-α-L-arabinosyluridine, and 2′-O-methyl-β-L-uridine were accomplished. Comparing their nuclear magnetic resonance (NMR) spectra and physical data, its structure was reassigned as 2′-O-methyl-β-L-uridine instead of former reported 2′-O-methyl-β-L-arabinosyluridine.
