Check Digit Verification of cas no

The CAS Registry Mumber 1807-47-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,8,0 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1807-47:
(6*1)+(5*8)+(4*0)+(3*7)+(2*4)+(1*7)=82
82 % 10 = 2
So 1807-47-2 is a valid CAS Registry Number.

Overcrowded 1,8-diazafluorenylidene-chalcoxanthenes. Introducing nitrogens at the fjord regions of bistricyclic aromatic enes

Levy, Amalia,Cohen, Shmuel,Agranat, Israel

, p. 2755 - 2763 (2003)

The effects of introducing nitrogen atoms in the fjord regions and chalcogen bridges on the conformations of overcrowded bistricyclic aromatic enes were studied. The structures were studied by 1H, 13C, 77Se and 125/s
