131172-67-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 131172-67-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,1,1,7 and 2 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 131172-67:
(8*1)+(7*3)+(6*1)+(5*1)+(4*7)+(3*2)+(2*6)+(1*7)=93
93 % 10 = 3
So 131172-67-3 is a valid CAS Registry Number.

Haloform cleavage of 2-trifluoroacetyl- and N-vinyl-2-trifluoroacetylpyrroles gives pyrrole-2-carboxylic acids and their N-vinyl derivatives in good yields; most of these compounds do not melt between 120-190 deg C, but rather decompose with CO2 evolution.
