75233-08-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 75233-08-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,3 and 3 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 75233-08:
(7*7)+(6*5)+(5*2)+(4*3)+(3*3)+(2*0)+(1*8)=118
118 % 10 = 8
So 75233-08-8 is a valid CAS Registry Number.

Lewis Acid Catalyzed Cycloaddition of Methyl 2,3-Butadienoate to Alkenes
Snider, Barry B.,Spindell, David K.
, p. 5017 - 5020 (2007/10/02)
Methyl 2,3-butadienoate (1) undergoes EtAlCl2-catalyzed stereospecific cycloadditions with alkenes to give methyl cyclobutylideneacetates in good yield.The stereospecificity and ratios of E and Z isomers suggest a ?2s + sub
