Check Digit Verification of cas no

The CAS Registry Mumber 64890-25-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,8,9 and 0 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 64890-25:
(7*6)+(6*4)+(5*8)+(4*9)+(3*0)+(2*2)+(1*5)=151
151 % 10 = 1
So 64890-25-1 is a valid CAS Registry Number.

Weak Interactions in Crystals: 4,4'-Di(tert-butyl)-N-N'-bipyridinium Diperchlorate - A Biphenyl Analogue with Perpendicular Pyridine Rings

Bock, Hans,Nick, Sabine,Naether, Christian,Bensch, Wolfgang

, p. 557 - 563 (2007/10/03)

Oxidation of substituted N-aminopyridinium compounds yields bipyridinium salts.After anion exchange Br(1-) --> ClO4(1-), it was possible to grow single crystals from the 4,4'-di(tert-butyl)derivative.The structure determined at 100 K shows a dihedral angl
