145511-01-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145511-01-9 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 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 145511-01:
(8*1)+(7*4)+(6*5)+(5*5)+(4*1)+(3*1)+(2*0)+(1*1)=99
99 % 10 = 9
So 145511-01-9 is a valid CAS Registry Number.

Heterocyclic spirocyclohexadienones, II
Mohrle,Schake
, p. 695 - 700 (2007/10/02)
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.
