Check Digit Verification of cas no
The CAS Registry Mumber 19815-21-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,8,1 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 19815-21:
(7*1)+(6*9)+(5*8)+(4*1)+(3*5)+(2*2)+(1*1)=125
125 % 10 = 5
So 19815-21-5 is a valid CAS Registry Number.

, p. 272 - 278 (2006)
A simple, efficient, and general method has been developed for the synthesis of various N-aryl heterocylic substituted-4-aminoquinazoline compounds from 4-chloro-quinazoline and aryl heterocyclic amines under microwave irradiation using 2-propanol as solvent. The advantages of the use of microwave irradiation in relation to the classical method were demonstrated.
