128885-97-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 128885-97-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,8,8,8 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 128885-97:
(8*1)+(7*2)+(6*8)+(5*8)+(4*8)+(3*5)+(2*9)+(1*7)=182
182 % 10 = 2
So 128885-97-2 is a valid CAS Registry Number.

Synthesis of Substituted Diphenyl Ethers using the Diels-Alder Reaction
Carter, Stephen D.,Thetford, Dean,Voyle, Martyn,Sammes, Peter G.
, p. 1231 - 1233 (2007/10/02)
The phenoxyfurans (4) and (8) undergo a Diels-Alder reaction with dimethyl acetylenedicarboxylate (DMAD) to give the cycloadducts (5) and (9) which can be converted into the substituted diphenyl ethers (6) and (10) respectively.
