1352717-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1352717-91-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,2,7,1 and 7 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1352717-91:
(9*1)+(8*3)+(7*5)+(6*2)+(5*7)+(4*1)+(3*7)+(2*9)+(1*1)=159
159 % 10 = 9
So 1352717-91-9 is a valid CAS Registry Number.

Preparation of 6-aminoquinazolin-4(3H)-ones via direct SNAr on the quinazoline ring
Barlaam, Bernard,Harris, Craig S.,Lecoq, Jonathan,Nguyen, Ha Thi Hoang
, p. 534 - 543 (2012/01/06)
The preparation of 6-aminoquinazolin-4(3H)-ones requires the use of platinum-metal group catalysis on the corresponding C-6-iodo or 6-bromo precursors. Herein, we report to our knowledge the first successful S NAr reaction directly at the unact
