Check Digit Verification of cas no

The CAS Registry Mumber 331240-36-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,1,2,4 and 0 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 331240-36:
(8*3)+(7*3)+(6*1)+(5*2)+(4*4)+(3*0)+(2*3)+(1*6)=89
89 % 10 = 9
So 331240-36-9 is a valid CAS Registry Number.

One-pot synthesis of quinazolinone and benzamide derivatives using SBA-Pr-SO3H as a nanoporous heterogeneous acid catalyst

Nahad, Monireh Shakiba,Ziarani, Ghodsi Mohammadi

, p. 1597 - 1603 (2013)

A series of quinazolinone and benzamide derivatives have been efficiently synthesized in good to excellent yields via the reaction of 2-aminobenzamide and aromatic benzoyl chlorides under solvent-free conditions using SBA-Pr-SO 3H as a nano solid acid catalyst.
