Check Digit Verification of cas no

The CAS Registry Mumber 64498-81-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,4,9 and 8 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 64498-81:
(7*6)+(6*4)+(5*4)+(4*9)+(3*8)+(2*8)+(1*1)=163
163 % 10 = 3
So 64498-81-3 is a valid CAS Registry Number.

One-pot synthesis of pyrrolo[3,2-f]-and pyrrolo[2,3-h]quinoline derivatives: Observation of an unexpected mechanistic pathway

Ramesh, Subburethinam,Nagarajan, Rajagopal

, p. 717 - 722 (2012/07/03)

One-pot synthesis of pyrrolo[3,2-f]- and pyrrolo[2,3-h]quinolines were obtained starting from substituted 5-aminoindoles, benzaldehydes, and phenylacetylenes in the presence of La(OTf)3 as a catalyst in good yields. The indole moiety in 5-aminoindole is believed to be mainly responsible for the observation of unexpected mechanistic pathway to the formation of pyrrolo[2,3-h]quinoline.
