Check Digit Verification of cas no
The CAS Registry Mumber 145510-99-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,5,1 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 145510-99:
(8*1)+(7*4)+(6*5)+(5*5)+(4*1)+(3*0)+(2*9)+(1*9)=122
122 % 10 = 2
So 145510-99-2 is a valid CAS Registry Number.

Heterocyclic spirocyclohexadienones, II
Mohrle,Schake
, p. 695 - 700 (1992)
Hofmann-Martius rearrangement of differently substituted aniline derivatives is investigated and the synthesis of spirocyclohexadienones 5 and 25 is performed. In comparison with 9, a N-aliphatic spiro compound, 5 and 25 give partially different reactions, the cause of which is discussed.
