Check Digit Verification of cas no

The CAS Registry Mumber 186505-74-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,6,5,0 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 186505-74:
(8*1)+(7*8)+(6*6)+(5*5)+(4*0)+(3*5)+(2*7)+(1*4)=158
158 % 10 = 8
So 186505-74-8 is a valid CAS Registry Number.

A novel and facile carbodiimide-mediated synthesis of 2,3-dihydro-6H-pyrimido[2,1-b]quinazolin-4(1H)-ones via a tandem intramolecular nucleophilic addition/intramolecular hetero conjugate addition annulation strategy

Saito, Takao,Tsuda, Kensaku

, p. 9071 - 9072 (1996)

A novel and efficient carbodiimide-mediated synthetic method for new 2,3-dihydro-6H-pyrimido[2,1-b]quinazolin-4(1H)-ones (4) is described which involves initial intramolecular addition of an amino-nucleophile to the carbodiimide-cumulenic system, followed by intramolecular hetero conjugate addition annulation.
