Check Digit Verification of cas no

The CAS Registry Mumber 749875-14-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,9,8,7 and 5 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 749875-14:
(8*7)+(7*4)+(6*9)+(5*8)+(4*7)+(3*5)+(2*1)+(1*4)=227
227 % 10 = 7
So 749875-14-7 is a valid CAS Registry Number.

Synthesis of Entecavir (BMS-200475)

Zhou, Bing,Li, Yuanchao

, p. 502 - 504 (2012)

A synthesis of Entecavir (BMS-200475) was achieved starting from 1,3-propanediol in 15 steps and 23.4% overall yield. A unique feature of the synthetic route is that the five-membered carbocyclic core is installed by an intramolecular nitrile oxide cycloaddition (INOC) reaction and the guanine moiety is introduced by a Mitsunobu reaction. The route is characteristic of low cost, high yield and easy operation.
