Check Digit Verification of cas no

The CAS Registry Mumber 1424350-98-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,4,3,5 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1424350-98:
(9*1)+(8*4)+(7*2)+(6*4)+(5*3)+(4*5)+(3*0)+(2*9)+(1*8)=140
140 % 10 = 0
So 1424350-98-0 is a valid CAS Registry Number.

Synthesis and structure of tetraarylcumulenes: Characterization of bond-length alternation versus molecule length

Januszewski, Johanna A.,Wendinger, Dominik,Methfessel, Christian D.,Hampel, Frank,Tykwinski, Rik R.

, p. 1817 - 1821 (2013/04/10)

BLA=0? Not so fast! A series of tetraarylcumulenes up to the length of a [9]cumulene has been synthesized and analyzed by X-ray crystallography. The structural data show a distinct reduction in bond-length alternation (BLA) as a function of molecule length, but this trend appears to reach a limit before a cumulenic structure with BLA=0 is achieved.
