Check Digit Verification of cas no

The CAS Registry Mumber 19725-73-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,2 and 5 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19725-73:
(7*1)+(6*9)+(5*7)+(4*2)+(3*5)+(2*7)+(1*3)=136
136 % 10 = 6
So 19725-73-6 is a valid CAS Registry Number.

Generation of Heterocyclic Quinone Methides from ortho-Hydroxy Methyl Derivatives and a Study of Their Cycloaddition Reactions

Chauncey, Marek A.,Grundon, Michael F.,Rutherford, Mary J.

, p. 527 - 529 (1988)

Quinolinone quinone methide (1a), prepared from 1,3-dimethyl-4-hydroxyquinolin-2-one and 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ), gives a dimer (5) and reacts in situ with 2,2-dimethyl-2H-1-benzopyran, and with isopropenyl acetate, to give Diels-Alder cycloaddition products; coumarin quinone methides behave similarly with 2,2-dimethylbenzopyran, but with isopropenyl acetate and with 2,3-benzofuran give adducts that probably result from cycloaddition reactions.
