Check Digit Verification of cas no

The CAS Registry Mumber 100465-53-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,4,6 and 5 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 100465-53:
(8*1)+(7*0)+(6*0)+(5*4)+(4*6)+(3*5)+(2*5)+(1*3)=80
80 % 10 = 0
So 100465-53-0 is a valid CAS Registry Number.

Chemistry of 4-trimethylsilyl-3-dialkylaminocrotonate esters and the cycloaromatization reactions with enamines

Kang, G. J.,Chan, T. H.

, p. 3102 - 3110 (2007/10/02)

Methyl 4-trimethylsilyl-3-dialkylaminocrotonate is synthesized by the silylation of methyl 3-dialkylaminocrotonate.It reacts with carbonyl electrophiles at its γ-position.The unusual regiochemistry of this reaction is studied and rationalized.It reacts with enamines derived from acyclic ketones to give aromatic compounds in a 3C+3C combination and with enamines derived from cycloketones of 5- to 8-membered rings to give aromatic compounds in a 4C+2C combination.A mechanism for this cycloaromatization reaction is proposed.
