Check Digit Verification of cas no

The CAS Registry Mumber 99707-91-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,7,0 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 99707-91:
(7*9)+(6*9)+(5*7)+(4*0)+(3*7)+(2*9)+(1*1)=192
192 % 10 = 2
So 99707-91-2 is a valid CAS Registry Number.

Thermolysis of Benzopyranone-Idenone Adducts. 2. Some New Aspects of the Mechanism

Vanderzande, Dirk J.,Kiekens, Eric G.,Martens Henri J.,Hoornaert, Georges J.

, p. 1019 - 1025 (2007/10/02)

Thermolysis of benzopyranone-indenone adducts 1, probably proceeding via o-quinodimethanes 10, gives C-nor-D-homo steroids 4, benzofluorenones 5, and traces of benzocyclopropafluorenones 6.Evidence is presented for the intervention of a biradica
