Check Digit Verification of cas no
The CAS Registry Mumber 150614-25-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,6,1 and 4 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 150614-25:
(8*1)+(7*5)+(6*0)+(5*6)+(4*1)+(3*4)+(2*2)+(1*5)=98
98 % 10 = 8
So 150614-25-8 is a valid CAS Registry Number.

Bis azaheterocycles: Part 1 - Synthesis of 3,3'-bisquinazolin-4,4'-diones
Reddy, P S N,Bhavani, A K
, p. 740 - 744 (2007/10/02)
1,2-Bis(2-aminobenzoyl)hydrazine (1a) reacts with aliphatic acids to yield 2,2'-dialkyl-3,3'-bisquinazolin-4,4'-diones (2).Extension of this reaction to aromatic aldehydes give a mixture of 2,2'-diaryl-tetrahydro-3,3'-bisquinazolin-4,4'-diones (6) and 1,2
