Check Digit Verification of cas no

The CAS Registry Mumber 19023-27-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,2 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19023-27:
(7*1)+(6*9)+(5*0)+(4*2)+(3*3)+(2*2)+(1*7)=89
89 % 10 = 9
So 19023-27-9 is a valid CAS Registry Number.

INFLUENCE OF THE NATURE OF THE BASE ELECTROLYTE ON THE REGIOSELECTIVITY OF THE CATHODIC HYDRODIMERIZATION OF 1-ACETYLNAPHTHALENE IN AN APROTIC MEDIUM

Gul'tyai, V. P.,Rubinskaya, T. Ya.,Mendkovich, A. S.

, p. 372 - 375 (2007/10/02)

The electrolysis of 1-acetylnaphthalene at a controlled potential (DMF, Ba(ClO4)2) leads to the formation of 5-acetyl-1,2,4,5-tetrahydro-2-methyl-2-(1-naphthyl)-1,4-methano-3-benzoxepine (yield of 60percent); this is explained by the stabilization of the dimeric dianion of the "Head-tail" type by the Ba2+ cations.The formation of 2,3-dimethyl-2,3-di-(1-naphthyl)-butane-2,3-diol is observed with the acylotropic rearrangement of the intermediate anion, leading to 2-acetylnaphthalene, in the presenc of lithium cations.
