Check Digit Verification of cas no
The CAS Registry Mumber 90002-40-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,0 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 90002-40:
(7*9)+(6*0)+(5*0)+(4*0)+(3*2)+(2*4)+(1*0)=77
77 % 10 = 7
So 90002-40-7 is a valid CAS Registry Number.

Different synthetic pathways are discussed for the title compounds 15 and 45, which can be trapped in solution.Their average lifetimes are to low for an isolation in pure state.Isomerisations on the C8H8-energy hypersurface lead to styrene (47) and/or benzocyclobutene (22).
