Check Digit Verification of cas no

The CAS Registry Mumber 303958-09-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,3,9,5 and 8 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 303958-09:
(8*3)+(7*0)+(6*3)+(5*9)+(4*5)+(3*8)+(2*0)+(1*9)=140
140 % 10 = 0
So 303958-09-0 is a valid CAS Registry Number.

Synthesis of picropodophyllin homolactone

Roulland, Emmanuel,Bertounesque, Emmanuel,Huel, Christiane,Monneret, Claude

, p. 6769 - 6773 (2000)

Based on a Wittig olefination strategy, the first synthesis of picropodophyllin homolactone 2 is described in nine steps and 30% overall yield from podophyllotoxine 1. The relative configuration of 2 was unambiguously determined using 2D NOESY NMR and a Monte Carlo search protocol. This work corrects the literature on the synthesis of 2.
