Check Digit Verification of cas no

The CAS Registry Mumber 157944-70-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,9,4 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 157944-70:
(8*1)+(7*5)+(6*7)+(5*9)+(4*4)+(3*4)+(2*7)+(1*0)=172
172 % 10 = 2
So 157944-70-2 is a valid CAS Registry Number.

Enantioselective total synthesis of (-)-chlorothricolide via the tandem inter- and intramolecular Diels-Alder reaction of a hexaenoate intermediate

Roush, William R.,Sciotti, Richard J.

, p. 7411 - 7419 (2007/10/03)

An enantioselective total synthesis of (-)-chlorothricolide (1) has been completed via a route involving the tandem inter- and intramolecular Dieis-Alder (IMDA) reaction of hexaenoate 19 and the chiral dienophile (R)-12. This reaction, which establishes s
