89567-88-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 89567-88-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,9,5,6 and 7 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 89567-88:
(7*8)+(6*9)+(5*5)+(4*6)+(3*7)+(2*8)+(1*8)=204
204 % 10 = 4
So 89567-88-4 is a valid CAS Registry Number.

THERMAL REARRANGEMENT OF O-THIOACYL DERIVATIVES OF N-ACYL-N-ARYLHYDROXYLAMINES
Drozd, V.N.
, p. 317 - 326 (2007/10/02)
The ability of the Ar-N-O-C=S system of atoms to undergo a thermal rearrangement of the Claisen type was investigated.On the basis of the experimental data it was concluded that the process is predominantly nonconcerted in nature.
