Check Digit Verification of cas no

The CAS Registry Mumber 83577-52-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,5,7 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83577-52:
(7*8)+(6*3)+(5*5)+(4*7)+(3*7)+(2*5)+(1*2)=160
160 % 10 = 0
So 83577-52-0 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.

Unexpected Regiochemistry in the Reaction of some γ-Trimethylsilylated 3-Dialkylamino-crotonate Esters with Carbonyl Electrophiles.

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

, p. 3011 - 3014 (2007/10/02)

4-Trimethylsilyl-3-dialkylaminocrotonate esters (4) react with a number of carbonyl electrophiles and titanium tetrachloride to give products with substitution at γ-position.A dynamic equilibrium of 4 and its O-silyl isomer 16 is proposed to explain the regiochemistry.
