Check Digit Verification of cas no

The CAS Registry Mumber 1569321-19-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,3,2 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1569321-19:
(9*1)+(8*5)+(7*6)+(6*9)+(5*3)+(4*2)+(3*1)+(2*1)+(1*9)=182
182 % 10 = 2
So 1569321-19-2 is a valid CAS Registry Number.

Copper-catalyzed domino synthesis of 4-oxopyrimido[1,2-a] indole derivatives

Wang, Yuyuan,Wang, Ruji,Jiang, Yuyang,Tan, Chunyan,Fu, Hua

, p. 2928 - 2935 (2013)

A novel, convenient and efficient copper-catalyzed domino method for the synthesis of 4-oxopyrimido[1,2-a]indole derivatives has been devel-oped, and the corresponding target products were obtained in moderate to good yields. The domino re-actions involved sequential copper-catalyzed inter-molecular C-arylation, intramolecular addition of NH to nitrile and nucleophilic attack of amino to carbonyl, and the obtained N-(2-halophenyl)-3-oxo-alkanamides carry various functional groups.
