55812-09-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55812-09-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,8,1 and 2 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 55812-09:
(7*5)+(6*5)+(5*8)+(4*1)+(3*2)+(2*0)+(1*9)=124
124 % 10 = 4
So 55812-09-4 is a valid CAS Registry Number.

SYNTHESIS OF QUINAZOLINES
Bergman, Jan,Brynolf, Anna,Elman, Bjoern,Vuorinen, Eino
, p. 3697 - 3706 (2007/10/02)
Grignard reagents reacted with 2-aminobenzonitrile to give the intermediate (10), which readily could be cyclized to quinazolines by reaction with carbonyl compounds (e.g. acid chlorides, anhydrides, formates and oxalates).The intermediate (10) and aldehy
