Check Digit Verification of cas no

The CAS Registry Mumber 1104640-57-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,0,4,6,4 and 0 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1104640-57:
(9*1)+(8*1)+(7*0)+(6*4)+(5*6)+(4*4)+(3*0)+(2*5)+(1*7)=104
104 % 10 = 4
So 1104640-57-4 is a valid CAS Registry Number.

Stereochemical features of addition of O- and C-nucleophiles to 5-(Het)aryl-2,3-dicyano-1-ethylpyrazinium salts

Verbitskii,Rusinov,Slepukhin,Grishakov,Ezhikova,Kodess,Charushin

, p. 302 - 310 (2008)

Stable σH-adducts of O- and C-nucleophiles were obtained with cations of 5-(het)aryl-2,3-dicyano-1-ethylpyrazinium, and their structure was investigated by X-ray diffraction analysis. Analytical separation was performed of 1,2-dihydropyrazines
