54043-66-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 54043-66-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,0,4 and 3 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 54043-66:
(7*5)+(6*4)+(5*0)+(4*4)+(3*3)+(2*6)+(1*6)=102
102 % 10 = 2
So 54043-66-2 is a valid CAS Registry Number.

A NEW REARRANGEMENT OF α-AZO ALCOHOLS INTO N-SUBSTITUTED BRIDGED BICYCLIC LACTAMS. A POSSIBLE MODEL FOR CONFORMATION-DEPENDENT REARRANGEMENT
Otsuka, Takashi,Tezuka, Takahiro
, p. 2081 - 2086 (2007/10/02)
A new thermal rearrangement of sterically crowded α-azo alcohols (2 and 4) into bridged bicyclic lactams (9 and 11) is reported. A mechanism for this rearrangement is proposed.
