Check Digit Verification of cas no

The CAS Registry Mumber 1448778-73-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,7,7 and 8 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1448778-73:
(9*1)+(8*4)+(7*4)+(6*8)+(5*7)+(4*7)+(3*8)+(2*7)+(1*3)=221
221 % 10 = 1
So 1448778-73-1 is a valid CAS Registry Number.

Pyrrolo[3,4-c]quinoline-1,3-dione derivatives and synthesis method thereof

-

Paragraph 0053; 0057; 0071-0074; 0312-0318, (2016/10/10)

The present invention relates to a synthesis method of a pyrrolo[3,4-c]quinoline-1,3-dione derivative, wherein different kinds of pyrrolo[3,4-c]quinoline-1,3-dione derivatives representing various biological activities can be manufactured with a high yield through one step reaction using a low-priced nonmetallic catalyst under a mild condition.COPYRIGHT KIPO 2015

Efficient one-step synthesis of pyrrolo[3,4-c]quinoline-1,3-dione derivatives by organocatalytic cascade reactions of isatins and β-ketoamides

Xia, Likai,Lee, Yong Rok

, p. 5254 - 5263 (2013/08/23)

We describe an efficient one-step synthesis of pyrrolo[3,4-c]quinolinedione derivatives using ethylenediamine diacetate (EDDA)-catalyzed cascade reactions of isatins and β-ketoamides. It is the first direct conversion of isatins to pyrrolo[3,4-c]quinolinedione derivatives via C-N bond cleavage and isatin ring expansion. Furthermore, this reaction provides a one-step synthetic route for the production of biologically interesting complex molecules that are generally prepared using multi-step reactions.
