64724-48-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 64724-48-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,7,2 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 64724-48:
(7*6)+(6*4)+(5*7)+(4*2)+(3*4)+(2*4)+(1*8)=137
137 % 10 = 7
So 64724-48-7 is a valid CAS Registry Number.

The Solvolysis of N-Acetoxy-2-acetylaminofluorene and N-Acetoxy-4-acetylaminobiphenyl: Delicate Balance between Nitrenium Ion Formation and Hydrolysis
Underwood, Graham R.,Kirsch, Robert B.
, p. 136 - 138 (2007/10/02)
The solvolysis of N-acetoxy-2-acetylaminofluorene in aqueous acetone at neutral pH proceeds exclusively with nitrenium ion formation while under the same conditions, the 4-aminobiphenyl analogue undergoes exclusive acyl-oxygen scission.
