116833-52-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116833-52-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,8,3 and 3 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 116833-52:
(8*1)+(7*1)+(6*6)+(5*8)+(4*3)+(3*3)+(2*5)+(1*2)=124
124 % 10 = 4
So 116833-52-4 is a valid CAS Registry Number.

18O-scrambling within the sulfonate during acetolysis of 18O-13C double-labeled β-arylalkyl tosylates was determinated by 13C NMR tracer analysis based on 18O-induced isotope shift.Ion-pair mechanism was discussed in comparison with presently accepted mechanism.
