Check Digit Verification of cas no

The CAS Registry Mumber 144950-26-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,9,5 and 0 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 144950-26:
(8*1)+(7*4)+(6*4)+(5*9)+(4*5)+(3*0)+(2*2)+(1*6)=135
135 % 10 = 5
So 144950-26-5 is a valid CAS Registry Number.

Synthesis and biological activity of 4'-thionucleosides of 2- chloroadenine

Tiwari,Secrist III,Montgomery

, p. 1819 - 1828 (2007/10/02)

1,2,3,5-Tetra-O-acetyl-4-thio-D-ribofuranose, prepared from 2,3,5-tri-O- benzyl-D-ribofuranose in four steps, was converted to the corresponding 2- chloroadenine nucleoside (8), which was deoxygenated to obtain 2-chloro-2'- deoxy-4'-thioadenosine (12). Th
