97094-34-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 97094-34-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,0,9 and 4 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 97094-34:
(7*9)+(6*7)+(5*0)+(4*9)+(3*4)+(2*3)+(1*4)=163
163 % 10 = 3
So 97094-34-3 is a valid CAS Registry Number.

, (2008/06/13)
Aromatic monomers, each containing at least one o-ethynyl carboxylic acid halide subunit: STR1 wherein X is Cl or Br. These monomers can be reacted with amines to form aromatic polyamide resins which can be thermally treated to undergo intromolecular cyclization, without evolution of volatiles, into polyimidines.
