Check Digit Verification of cas no

The CAS Registry Mumber 1173913-69-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,7,3,9,1 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1173913-69:
(9*1)+(8*1)+(7*7)+(6*3)+(5*9)+(4*1)+(3*3)+(2*6)+(1*9)=163
163 % 10 = 3
So 1173913-69-3 is a valid CAS Registry Number.

Synthesis of indolylquinolines, indolylacridines, and indolylcyclopenta[b] quinolines from the Baylis-Hillman adducts: An in situ [1,3]-sigmatropic rearrangement of an indole nucleus to access indolylacridines and indolylcyclopenta[b]quinolines

, p. 8451 - 8464 (2012/11/07)

A simple and easy route to the synthesis of a variety of structurally diverse indolylquinolines, indolylacridines, and indolylcyclopenta[b]quinoline derivatives via the reductive cyclization of C-alkylated indole derivatives, derived from acyclic as well as cyclic Baylis-Hillman adducts with indoles, is described. An unusual in situ [1,3]-sigmatropic rearrangement of the indole nucleus was observed during the reductive cyclicization of α- regioselective B-H adducts containing indoles to produce indolylacridines and indolylcyclopenta[b]quinoline derivatives.
