Check Digit Verification of cas no

The CAS Registry Mumber 320576-76-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,0,5,7 and 6 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 320576-76:
(8*3)+(7*2)+(6*0)+(5*5)+(4*7)+(3*6)+(2*7)+(1*6)=129
129 % 10 = 9
So 320576-76-9 is a valid CAS Registry Number.

Microwave-promoted, one-pot, solvent-free synthesis of 4-arylcoumarins from 2-hydroxybenzophenones

Crecente-Campo, Jose,Vazquez-Tato, M. Pilar,Seijas, Julio A.

experimental part, p. 4130 - 4135 (2010/09/18)

4-Arylcoumarins are synthesized in very good yields through solvent-free microwave irradiation of 2-hydroxybenzophenones and alkyl malonate in the presence of DBU. The onepot synthesis is carried out with Knoevenagel condensation, intramolecular lactonization, and decarboxylation reactions. The method can be applied to a broad scope of neoflavonoids.
