Check Digit Verification of cas no

The CAS Registry Mumber 1182228-53-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,8,2,2,2 and 8 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1182228-53:
(9*1)+(8*1)+(7*8)+(6*2)+(5*2)+(4*2)+(3*8)+(2*5)+(1*3)=140
140 % 10 = 0
So 1182228-53-0 is a valid CAS Registry Number.

Construction of enantioenriched cyclic compounds by asymmetric allylic alkylation and ring-closing metathesis

Giacomina, Francesca,Alexakis, Alexandre

, p. 6710 - 6721 (2013)

A new approach to highly enantioenriched cyclic compounds (up to 98a€‰% ee) has been developed by using ω-ethylenic allylic substrates in a one-pot asymmetric allylic alkylation and ring-closing metathesis sequence. The starting compounds are synthetic equivalents of cyclic allylic substrates. The method is exemplified with both Cu and Ir catalysts, and chiral phosphoramidite ligands.
