Check Digit Verification of cas no

The CAS Registry Mumber 106476-87-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,4,7 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 106476-87:
(8*1)+(7*0)+(6*6)+(5*4)+(4*7)+(3*6)+(2*8)+(1*7)=133
133 % 10 = 3
So 106476-87-3 is a valid CAS Registry Number.

Formation of 2-cyclohexenones by Friedel-Crafts acylation of alkenes with β,γ-ethylenic acyl halides

Faure,Pommier,Pons,Rajzmann,Santelli

, p. 8419 - 8430 (2007/10/02)

Friedel-Crafts acylation of alkenes with β,γ-alkenoyl halides leads to conjugated Al-trienolates able to cyclize into Al-enolates of 2-cyclohexenones through an allowed thermal disrotary electrocyclization mechanism. Discussion of the product structures is based on two-dimensional NMR experiments (400 MHz) and molecular mechanics studies (GENMOL and MM2).
