77943-93-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 77943-93-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,9,4 and 3 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77943-93:
(7*7)+(6*7)+(5*9)+(4*4)+(3*3)+(2*9)+(1*3)=182
182 % 10 = 2
So 77943-93-2 is a valid CAS Registry Number.

The three dioxa-tris--?-homobenzenes (5)-(7) have been synthesised.Preliminary thermolysis experiments in the gas-phase (300-400 deg C)allow a qualitative description of their thermal isomerisation processes.
