Check Digit Verification of cas no

The CAS Registry Mumber 157131-88-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,1,3 and 1 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 157131-88:
(8*1)+(7*5)+(6*7)+(5*1)+(4*3)+(3*1)+(2*8)+(1*8)=129
129 % 10 = 9
So 157131-88-9 is a valid CAS Registry Number.

Synthetic and Kinetic Studies of Substituent Effects in the Furan Intramolecular Diel-Alder Reaction

McNelis, Brian J.,Sternbach, Daniel D.,MacPhail, Andrew T.

, p. 6767 - 6782 (1994)

The intramolecular Diels-Alder reactions (IMDA) of a series of 2-sulfone substituted 1-furyl-4-penten-1-ols, 5a-c, have been studied.As the steric demands of the alkyl group on the sulfone was increased the rate and the product yields in the IMDA reaction have also been observed to increase.The kinetics of these systems have been studied in detail as well as solvent effects to quantify substituent group effects in the cyclization reactions.Activated dienophiles (CO2Me) in these systems have been shown to be very reactive, cyclizing at ambient temperature.
