Check Digit Verification of cas no

The CAS Registry Mumber 76583-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,5,8 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76583-45:
(7*7)+(6*6)+(5*5)+(4*8)+(3*3)+(2*4)+(1*5)=164
164 % 10 = 4
So 76583-45-4 is a valid CAS Registry Number.

Substituent Effects in the Cycloaddition Reactions of Reissert Hydrofluoroborate Salts with Alkenes

McEwen, William E.,Hernandez, Maria Alcira,Ling, Chei-Fei,Marmugi, Elba,Padronaggio, Regina M.,et al.

, p. 1656 - 1662 (2007/10/02)

An evaluation of substitutent effects has been undertaken of the cycloaddition of 2-aroyl-1,2-dihydroisoquinaldonitrile hydrofluoroborates (5) with substituted ethyl cinnamates, styrenes, stilbenes, and ethylenes.The cinnamates give mixtures of 2-(1-isoquinolyl)-3,5-diaryl-4-carbethoxypyrroles.The stilbenes give mixtures of 2-(1-isoquinolyl)-3,4,5-triarylpyrroles, but the styrenes give only 2-(1-isoquinolyl)-3,5-diarylpyrroles. 1-Hexene and cyclohexene undergo cycloaddition with 5 (Y=H) readily, but 2-heptene does not.The rates of many these reactions have been determined.The implications of the results with respect to the mechanism of reaction are discussed.
