Check Digit Verification of cas no

The CAS Registry Mumber 2513-66-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,1 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2513-66:
(6*2)+(5*5)+(4*1)+(3*3)+(2*6)+(1*6)=68
68 % 10 = 8
So 2513-66-8 is a valid CAS Registry Number.

BENTONITE K10 CLAY, AN EFFICIENT CATALYST FOR THE FORMATION OF NITROGEN DERIVATIVES

Eynde, Jean Jacques Vanden,Mayence, Annie,Lor, Pascal,Haverbeke, Yves Van

, p. 387 - 392 (2007/10/02)

Bentonite K10 clay has been used to catalyze the formation of enamino carbonyl derivatives, 2-methyl-1H-benzimidazoles, Hantzsch 1,4-dihydropyridines, Hantzsch pyridines, 2-substituted 1,3-diphenylimidazolidines, and tetrahydropyranylbenzazoles.

NOVEL SYNTHESES OF HETEROCYCLES WITH N-(1-HALOALKYL)AZINIUM HALIDES PART 1. PREPARATION OF IMIDAZOLIDINES

Eynde, J.-J. Vanden,Mayence, A.,Maquestiau, A.,Anders, E.

, p. 233 - 236 (2007/10/02)

N-(1-Chloroalkyl)pyridinium chlorides, prepared from thionyl chloride, pyridine, and an aldehyde, readily react with N,N'-disubstituted 1,2-ethanediamine to yield imidazolidines under mild and neutral conditions.
