Check Digit Verification of cas no
The CAS Registry Mumber 1618654-27-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,8,6,5 and 4 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1618654-27:
(9*1)+(8*6)+(7*1)+(6*8)+(5*6)+(4*5)+(3*4)+(2*2)+(1*7)=185
185 % 10 = 5
So 1618654-27-5 is a valid CAS Registry Number.

An efficient metal-free synthesis of 2-amino-substituted-4(3H)-quinazolinones
Mirza, Behrooz
, p. 146 - 147 (2015/12/23)
2-Amino-substituted-4(3H)-quinazolinones have been synthesized via an efficient metal-free reaction between 2-aminobenzamide derivatives and carbonimidic dibromides. The reaction proceeds in the presence of K2CO3 affording cyclized products in good to excellent yields.
