Check Digit Verification of cas no

The CAS Registry Mumber 28448-10-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,4,4 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 28448-10:
(7*2)+(6*8)+(5*4)+(4*4)+(3*8)+(2*1)+(1*0)=124
124 % 10 = 4
So 28448-10-4 is a valid CAS Registry Number.

Synthesis of Cyanosubstituted Di- and Tetrahydropyridines in DIMCARB (Dimethylamine-CO2-Adduct)

Dunkel,Hess,Reck

, p. 414 - 419 (1997)

A new selective method for base-catalyzed ring closure reaction of acetophenones (1a-1) with malononitrile in DIMCARB (dimethylamine-CO2-addition-compound) as solvent of high dimethy lamine concentration is reported, which allows effective syntheses of (1.2-dihydro-4-pyrid-6-yl)dicyanomethanides and 5-cyano-6-dicyanomethylene-1,2,3,6-tetrahydropyridines in good yields. The structure of the two new classes of compounds is proved by X-ray diffraction analysis.
