Check Digit Verification of cas no

The CAS Registry Mumber 642067-56-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,2,0,6 and 7 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 642067-56:
(8*6)+(7*4)+(6*2)+(5*0)+(4*6)+(3*7)+(2*5)+(1*6)=149
149 % 10 = 9
So 642067-56-9 is a valid CAS Registry Number.

Diastereoselective intramolecular Diels-Alder reactions of masked o-benzoquinones: A short entry to highly functionalized tricyclic [m.2.2.0] ring systems

Chen,Peddinti,Liao

, p. 1340 - 1341 (2007/10/03)

Masked o-benzoquinones bearing a chiral center in the carbon-tether with a terminal olefin underwent diastereoselective intramolecular Diels-Alder reactions resulting in highly functionalized tricyclic ring systems.
