Check Digit Verification of cas no

The CAS Registry Mumber 76170-28-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,1,7 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 76170-28:
(7*7)+(6*6)+(5*1)+(4*7)+(3*0)+(2*2)+(1*8)=130
130 % 10 = 0
So 76170-28-0 is a valid CAS Registry Number.

Addition to bicyclobutane derivatives. IV. Stereochemistry of the addition of secondary amines to bicyclobutane-1-carbonitrile and 3-methylbicyclobutane-1-carbonitrile

Razin, V. V.,Vasin, V. A.,Ogloblin K. A.

, p. 671 - 679 (2007/10/02)

Secondary amines (dimethylamine, diethylamine, pyrrolidine, piperidine, and morpholine) add to bicyclobutane-1-carbonitrile and 3-methylbicyclobutane-1-carbonitrile exclusively at the central C-C bond with nucleophilic attack at the β position in relation to the nitrile group.The reactions are not stereospecific, but they are all cis-stereoselective.It was found that the structure of the substrate and the reagent and also the nature of the solvent have effects on the stereochemistry of addition.
