Check Digit Verification of cas no

The CAS Registry Mumber 146135-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,6,1,3 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 146135-89:
(8*1)+(7*4)+(6*6)+(5*1)+(4*3)+(3*5)+(2*8)+(1*9)=129
129 % 10 = 9
So 146135-89-9 is a valid CAS Registry Number.

CYCLIZATION OF ACETYLENIC DERIVATIVES OF AROMATIC CARBOXYLIC ACIDS

Ivanchikova, I. D.,Usubalieva, G. E.,Schastnev, P. V.,Moroz, A. A.,Shvartsberg, M. S.

, p. 1672 - 1679 (2007/10/02)

The Cu(I)-catalyzed intramolecular cyclization of 1-phenylethynyl- and 1-hexyn-1-yl-anthraquinone-2-carboxylic acid is a 6-endo-dig-addition, whereas the reaction for 1-(3-phenoxypropyn-1-yl)anthraquinone-2-carboxylic acid proceeds in a directionally nonspecific way.It is shown that the cyclization of vicinal acetylenic derivatives of aromatic carboxylic acids leads to the formation of the more stable of the possible cyclic structures. Keywords: 1-phenylethynylanthraquinone-2-carboxylic acid, 1-hexyn-1-yl-anthraquinone-2-carboxylic acid, 1-(3-phenoxypropyn-1-yl)anthraquinone-2-carboxylic acid, intramolecular cyclization, MNDO calculation method.
