21066-63-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21066-63-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,0,6 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21066-63:
(7*2)+(6*1)+(5*0)+(4*6)+(3*6)+(2*6)+(1*3)=77
77 % 10 = 7
So 21066-63-7 is a valid CAS Registry Number.

Evidence for a nonradical pathway in the photoracemization of aryl sulfoxides
Vos, Brian W.,Jenks, William S.
, p. 2544 - 2547 (2002)
Photolysis of (Rs,Sc)-1-deuterio-2,2-dimethylpropyl p-tolyl sulfoxide provides mainly (Ss,Sc)-1-deuterio-2,2-dimethylpropyl p-tolyl sulfoxide at low conversion, though the other two stereoisomers are formed to s
