1197934-71-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1197934-71-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,7,9,3 and 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1197934-71:
(9*1)+(8*1)+(7*9)+(6*7)+(5*9)+(4*3)+(3*4)+(2*7)+(1*1)=206
206 % 10 = 6
So 1197934-71-6 is a valid CAS Registry Number.

Synthesis of 2-amino-3,4-dihydroquinazolines and imidazo[2,1-b]quinazoline- 2-ones
Mishra, Amita,Batra, Sanjay
experimental part, p. 3077 - 3088 (2009/12/28)
A straightforward method for the synthesis of 2-amino-3,4- dihydroquinazolines from Baylis-Hillman derivatives is disclosed. The protocol involves sequential SN2 reaction of a primary amine on the Baylis-Hillman acetate derived from 2-nitrobenzaldehyde, c
