244032-56-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 244032-56-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,4,0,3 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 244032-56:
(8*2)+(7*4)+(6*4)+(5*0)+(4*3)+(3*2)+(2*5)+(1*6)=102
102 % 10 = 2
So 244032-56-2 is a valid CAS Registry Number.

Synthesis of some 6-aryl-benzimidazo[1,2-c]quinazolines 4 have been critically investigated. The first method, based on the condensation of substituted-1,3-benzoxazin-4-(3H)-one 2 with o-phenylenediamine followed by cyclization of the resulting 2-aryl-3-(
