Check Digit Verification of cas no

The CAS Registry Mumber 143582-49-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,8 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143582-49:
(8*1)+(7*4)+(6*3)+(5*5)+(4*8)+(3*2)+(2*4)+(1*9)=134
134 % 10 = 4
So 143582-49-4 is a valid CAS Registry Number.

4(3H)-Quinazolinones from the reaction of N-arylnitrilium salts with isocyanates

Al-Talib,Jochims,Hamed,Wang,Ismail

, p. 697 - 701 (1992)

N-Arylnitrilium salts 1 react with isocyanates 2 to give salts 3 of 4(3H)-quinazolinones 4, from which compounds 4 can be obtained with base. A metathesis of an isocyanate with a nitrilium salt is reported.
