Check Digit Verification of cas no

The CAS Registry Mumber 497157-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,7,1,5 and 7 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 497157-85:
(8*4)+(7*9)+(6*7)+(5*1)+(4*5)+(3*7)+(2*8)+(1*5)=204
204 % 10 = 4
So 497157-85-4 is a valid CAS Registry Number.

Diastereoselective synthesis of 4,5-dihydrofurans by iodoenolcyclisation of 2-allyl-1,3-dicarbonyl compounds

Antonioletti, Roberto,Malancona, Savina,Bovicelli, Paolo

, p. 8825 - 8831 (2002)

A study of the stereochemical aspects of I2-induced cyclisation of 2-alkenyl-1,3-dicarbonyl compounds reveals that the iodoenolcyclisation is strictly dependent on the dicarbonyl species and the substituents in the allylic position.
