Check Digit Verification of cas no
The CAS Registry Mumber 2997-45-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,9 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 2997-45:
(6*2)+(5*9)+(4*9)+(3*7)+(2*4)+(1*5)=127
127 % 10 = 7
So 2997-45-7 is a valid CAS Registry Number.

Attempted synthesis of Fjord-region containing polycyclic fluoranthenes reveals a steric-driven double Wagner-Meerwein rearrangement
Cho, Bongsup P.,Zhou, Li
, p. 1535 - 1538 (2007/10/03)
A double Wagner-Meerwein rearrangement takes place commonly in the synthesis of sterically hindered polycyclic fluoranthenes via cyclodehydration reactions and the extent of intramolecular steric crowding within the initially formed tertiary cationic intermediate controls the equilibrium between the expected and the rearranged product.
