Check Digit Verification of cas no

The CAS Registry Mumber 560132-06-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,0,1,3 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 560132-06:
(8*5)+(7*6)+(6*0)+(5*1)+(4*3)+(3*2)+(2*0)+(1*6)=111
111 % 10 = 1
So 560132-06-1 is a valid CAS Registry Number.

Highly diastereoselective intramolecular Diels-Alder reaction of chiral silatrienes

Coelho, Paulo J.,Blanco, Luis

, p. 2451 - 2456 (2007/10/03)

New Si-chiral 2-silahexa-3,5-dienyl acrylates were prepared in six steps from dichloro(chloromethyl)methylsilane. The EtAlCl2 catalysed intramolecular Diels-Alder reaction of these compounds gave chiral 4-sila-4a,7,8,8a-tetrahydroisochroman-1-ones in good yield. Very good diastereoselectivity was observed for a silatriene bearing a methyl and a 2-methoxyphenyl substituent on the chiral silicon atom.
