524052-47-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 524052-47-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,2,4,0,5 and 2 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 524052-47:
(8*5)+(7*2)+(6*4)+(5*0)+(4*5)+(3*2)+(2*4)+(1*7)=119
119 % 10 = 9
So 524052-47-9 is a valid CAS Registry Number.

Synthesis of substituted dibenz[b,f]oxepines from 2,4,6-trinitrotoluene
Samet,Marshalkin,Lyssenko,Semenov
experimental part, p. 347 - 350 (2010/07/09)
1,3-Dinitro[b,f]dibenzoxepine undergoes nucleophilic substitution with O-and S-nucleophiles, the nitro group at position 1 (peri-nitro group) being selectively replaced. The factors responsible for the selectivity of the reaction are discussed.
