19912-83-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19912-83-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,9,1 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 19912-83:
(7*1)+(6*9)+(5*9)+(4*1)+(3*2)+(2*8)+(1*3)=135
135 % 10 = 5
So 19912-83-5 is a valid CAS Registry Number.

, p. 362 - 374 (2001)
The transformations of (-)-thujopsene in liquid (HSO3F-SO2FCl) and over solid (TiO2/SO24) superacids, as well as by the action of peroxy acids, were studied. New tricyclic hydrocarbons were isolated.
