1069137-87-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1069137-87-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,6,9,1,3 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1069137-87:
(9*1)+(8*0)+(7*6)+(6*9)+(5*1)+(4*3)+(3*7)+(2*8)+(1*7)=166
166 % 10 = 6
So 1069137-87-6 is a valid CAS Registry Number.

Zinc triflate-catalyzed synthesis of pyrazino[2,1-b]quinazoline-3,6-diones
Tseng, Ming-Chung,Chu, Yen-Ho
, p. 9515 - 9520 (2008/12/22)
Using zinc triflate, the direct one-pot double cyclodehydration of linear tripeptides to the total synthesis of pyrazino[2,1-b]quinazoline-3,6-diones (1a-l) on solid support was achieved with good overall yields in short reaction time. These syntheses of
