Check Digit Verification of cas no

The CAS Registry Mumber 3787-28-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,7,8 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 3787-28:
(6*3)+(5*7)+(4*8)+(3*7)+(2*2)+(1*8)=118
118 % 10 = 8
So 3787-28-8 is a valid CAS Registry Number.

Chemistry of polyhalogenated nitrobutadienes, part 9: Acyclic and heterocyclic nitroenamines and nitroimines from 2-nitroperchlorobuta-1,3-diene

Zapol'skii, Viktor A.,Namyslo, Jan C.,Gjikaj, Mimoza,Kaufmann, Dieter E.

experimental part, p. 843 - 860 (2011/01/11)

Various amino, diamino, aminothio, or benzotriazolo compounds derived from the exceedingly versatile 2-nitroperchlorobutadiene (1) gave structurally interesting and physiologically promising nitro-enamines,-imines,-amidines, and hydrazines as well as ring closure reaction products, e. g. pyrimidines and pyrazoles. Most of these reactions turned out to be highly selective with good to very good yields. The structure of the pyrazole precursor (E,E)-1-(benzotriazol-1-yl)-4,4-dichloro-3-(4-ethoxyphenylamino) -1-(4-ethoxyphenylimino)-2-nitrobut-2-ene (30), due to its exceptional substitution pattern, was evidenced by single-crystal X-ray diffraction analysis.
