Check Digit Verification of cas no

The CAS Registry Mumber 1239903-58-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,9,9,0 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1239903-58:
(9*1)+(8*2)+(7*3)+(6*9)+(5*9)+(4*0)+(3*3)+(2*5)+(1*8)=172
172 % 10 = 2
So 1239903-58-2 is a valid CAS Registry Number.

One-step synthesis of quinazolino[3,2-a ]quinazolinones via palladium-catalyzed domino addition/carboxamidation reactions

Zeng, Fanlong,Alper, Howard

supporting information; experimental part, p. 3642 - 3644 (2010/10/02)

A highly efficient palladium-catalyzed domino process has been developed for the synthesis of quinazolino[3,2-a]quinazolinones by forming five new bonds in a single step. Despite the high density and variety of functional groups on the substrates, the tetracyclic quinazolinones were obtained in good to excellent yields.
