68263-68-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 68263-68-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,2,6 and 3 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68263-68:
(7*6)+(6*8)+(5*2)+(4*6)+(3*3)+(2*6)+(1*8)=153
153 % 10 = 3
So 68263-68-3 is a valid CAS Registry Number.

Synthesis and oxidation of sulfides based on caryophyllene oxide and phenylmethanethiol
Gyrdymova, Yu. V.,Izmest’ev,Rubtsova,Kutchin
, p. 332 - 338 (2016)
Lewis acid-catalyzed reaction of (–)-caryophyllene oxide with phenylmethanethiol gave sulfides with clovane and caryophyllane structure which were oxidized to the corresponding sulfoxides and sulfones in 74 and 84% yield, respectively.
