Check Digit Verification of cas no

The CAS Registry Mumber 1340478-17-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,0,4,7 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1340478-17:
(9*1)+(8*3)+(7*4)+(6*0)+(5*4)+(4*7)+(3*8)+(2*1)+(1*7)=142
142 % 10 = 2
So 1340478-17-2 is a valid CAS Registry Number.

Asymmetric total syntheses of heliannuol e and epi-heliannuol e

Liu, Yongjiang,Huang, Chong,Liu, Bo

, p. 5802 - 5804 (2011)

Asymmetric total syntheses of heliannuol E and epi-heliannuol E were achieved in 10 and 13 steps, respectively, from the commercially available starting materials. The syntheses feature an intramolecular attacking on the sulfate to form the dihydropyran ring of heliannuol E and an acyl transfer-secondary carbocation capture sequence to construct the dihydropyran ring of epi-heliannuol E.
