Check Digit Verification of cas no

The CAS Registry Mumber 691857-52-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,9,1,8,5 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 691857-52:
(8*6)+(7*9)+(6*1)+(5*8)+(4*5)+(3*7)+(2*5)+(1*2)=210
210 % 10 = 0
So 691857-52-0 is a valid CAS Registry Number.

Conversion of a Benzofuran Ester to an Amide through an Enamine Lactone Pathway: Synthesis of HCV Polymerase Inhibitor GSK852A

Bowman, Roy K.,Bullock, Kae M.,Copley, Royston C. B.,Deschamps, Nicole M.,McClure, Michael S.,Powers, Jeremiah D.,Wolters, Andy M.,Wu, Lianming,Xie, Shiping

, p. 9610 - 9619 (2015)

HCV NS5B polymerase inhibitor GSK852A (1) was synthesized in only five steps from ethyl 4-fluorobenzoylacetate (3) in 46% overall yield. Key to the efficient route was the synthesis of the highly functionalized benzofuran core 15 from the β-keto ester in
