Check Digit Verification of cas no

The CAS Registry Mumber 1448670-20-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,8,6,7 and 0 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1448670-20:
(9*1)+(8*4)+(7*4)+(6*8)+(5*6)+(4*7)+(3*0)+(2*2)+(1*0)=179
179 % 10 = 9
So 1448670-20-9 is a valid CAS Registry Number.

One-pot ring-closing metathesis/1,3-dipolar cycloaddition through assisted tandem ruthenium catalysis: Synthesis of a dye with isoindolo[2,1-a]quinoline structure

Arisawa, Mitsuhiro,Fujii, Yuki,Kato, Hiroshige,Fukuda, Hayato,Matsumoto, Takashi,Ito, Mika,Abe, Hiroshi,Ito, Yoshihiro,Shuto, Satoshi

, p. 1003 - 1007 (2013/03/13)

The one-pot tandem reaction of N-alkyl-N-allyl-2-vinylaniline derivatives with benzo- or naphthoquinones and a ruthenium-alkylidene catalyst leads to isoindolo[2,1-a]quinolines in a variety of colors, which can be altered by exchanging the substituent on the core heterocycle (see scheme). This reaction offers a new synthetic method for π-conjugated small molecules from simple aniline derivatives. Copyright
