Check Digit Verification of cas no

The CAS Registry Mumber 14985-78-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,9,8 and 5 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 14985-78:
(7*1)+(6*4)+(5*9)+(4*8)+(3*5)+(2*7)+(1*8)=145
145 % 10 = 5
So 14985-78-5 is a valid CAS Registry Number.

Improved synthesis of β-D-6-methylpurine riboside and antitumor effects of the β-D- and α-D-anomers

Marasco Jr., Canio J.,Pera, Paula J.,Spiess, Arthur J.,Bernacki, Ralph,Sufrin, Janice R.

, p. 1015 - 1020 (2005)

6-Methylpurine-β-D-riboside (β-D-MPR) has been synthesized by coupling 6-methylpurine and 1-O-acety1-2,3,5-tri-O-benzoyl-D-ribose using conditions that produce the β-D-anomer exclusively. The in vitro antitumor effects of β-D-MPR and 6-methyl-purine-α-D-riboside (α-D-MPR) in five human tumor cell lines showed that β-D-MPR was highly active (IC50 values ranging from 6 to 34 nM). a-D-MPR, although less active than β-D-MPR, also exhibited significant antitumor effects (IC50 values ranging from 1.47 to 4.83 μM).
