Check Digit Verification of cas no

The CAS Registry Mumber 1360563-84-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,6,0,5,6 and 3 respectively; the second part has 2 digits, 8 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1360563-84:
(9*1)+(8*3)+(7*6)+(6*0)+(5*5)+(4*6)+(3*3)+(2*8)+(1*4)=153
153 % 10 = 3
So 1360563-84-3 is a valid CAS Registry Number.

Lewis acid-catalyzed Diels-Alder reaction of 2-cyclopentenones with Danishefsky's diene: Double bond isomerization of tetrahydro-1Hindene- 1,5(7aH)-diones, and attempts on an asymmetric catalysis

Krebs, Michael,Laschat, Sabine

experimental part, p. 5 - 19 (2012/03/11)

This work describes the investigation of the Diels-Alder reaction of the electron-rich diene trans- 1-methoxy-3-trimethylsilyloxy-1,3-butadiene (Danishefsky's diene) and the non-activated dienophiles 2-cyclopentenone and 2-methyl-2-cyclopentenone with respect to reactivity, regioselectivity and stereoselectivity. An observed double bond isomerization limits the practicability of 2-cyclopentenone as a dienophile in Diels-Alder reactions. 2-Methyl-2- cylopentenone could be converted quantitatively into one regioisomeric Diels-Alder adduct, however the stereochemical control turned out to be very demanding.
