Check Digit Verification of cas no

The CAS Registry Mumber 1403953-33-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,3,9,5 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1403953-33:
(9*1)+(8*4)+(7*0)+(6*3)+(5*9)+(4*5)+(3*3)+(2*3)+(1*3)=142
142 % 10 = 2
So 1403953-33-2 is a valid CAS Registry Number.

Asymmetric synthesis of a highly functionalized enantioenriched system close to thapsigargin framework

Tap, Aurelien,Galvani, Gilles,Sorin, Geoffroy,Lannou, Marie-Isabelle,Ardisson, Janick,Jouanneau, Morgan,Ferezou, Jean-Pierre

, p. 8140 - 8146,7 (2012/12/11)

A straightforward approach to a highly functionalized enantioenriched bicyclo[5.3.0]decadienone system close to the thapsigargin framework has been achieved. The developed synthetic route involves two main stages: installation of the chains on either side of the quaternary center at C7 starting from a central enantiopure epoxide and formation of the bicyclic octahydroazulene through subsequent Pauson-Khand annelation.
