Check Digit Verification of cas no

The CAS Registry Mumber 1228030-63-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,0,3 and 0 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1228030-63:
(9*1)+(8*2)+(7*2)+(6*8)+(5*0)+(4*3)+(3*0)+(2*6)+(1*3)=114
114 % 10 = 4
So 1228030-63-4 is a valid CAS Registry Number.

One-step and Solvent-free synthesis of terpene-fused pyrazines

Kulhanek, Jiri,Ludwig, Miroslav,Bures, Filip

experimental part, p. 315 - 322 (2010/08/04)

Solvent-free condensation reactions were carried out by heating terpene-monooximes with an excess of amines. Employing camphor-and nopinone-derived monooximes, two classes of terpene-fused pyrazine derivatives were synthesized. Besides being solvent-free, the described one-step procedure can be directed towards terpene-fused imidazole or pyrazine derivatives. Whereas the reaction worked well with arylmethanamines bearing a (hetero)aromatic substituent at the α-carbon, alkylamines afforded only imino-oximes. A possible reaction path is presented.
