Check Digit Verification of cas no

The CAS Registry Mumber 495386-38-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,5,3,8 and 6 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 495386-38:
(8*4)+(7*9)+(6*5)+(5*3)+(4*8)+(3*6)+(2*3)+(1*8)=204
204 % 10 = 4
So 495386-38-4 is a valid CAS Registry Number.

Molybdenum-mediated synthesis of quinazolin-4(3H)-ones via cyclocarbonylation using microwave irradiation

Roberts, Bryan,Liptrot, David,Luker, Tim,Stocks, Michael J.,Barber, Catherine,Webb, Nicola,Dods, Robert,Martin, Barrie

supporting information; experimental part, p. 3793 - 3796 (2011/08/06)

A new, efficient and practical synthesis of quinazolin-4(3H)-ones is reported via molybdenum-mediated cyclocarbonylation using microwave irradiation. These methods allow access to a wide range of quinazolin-4(3H)-ones in reasonable yields without the need for gaseous carbon monoxide and palladium catalysts. A range of reactions illustrating the wide scope of this chemistry was carried out and all proceeded in reasonable yields.
