Check Digit Verification of cas no

The CAS Registry Mumber 64942-17-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,9,4 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 64942-17:
(7*6)+(6*4)+(5*9)+(4*4)+(3*2)+(2*1)+(1*7)=142
142 % 10 = 2
So 64942-17-2 is a valid CAS Registry Number.

2,5-Bis(cyanimino)-2,5-dihydrothienothiophene - ein neuer Acceptortyp: Synthese und allgemeine Eigenschaften

Guenther, Erhard,Huenig, Siegfried

, p. 1235 - 1242 (2007/10/02)

The synthesis of a variety of substituted 2,5-bis(cyanoimino)-2,5-dihydrothienothiophenes (4) and the corresponding diones (5) is described.Different substituents on the acceptors 4 and 5 allow the redox potentials of these reversible two-step redox systems to be varied over a wide range. Key Words: Redox systems / Electron transfer / Hetero quinones / Electron acceptors / Thienothiophene derivatives
