112881-99-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112881-99-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,8,8 and 1 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 112881-99:
(8*1)+(7*1)+(6*2)+(5*8)+(4*8)+(3*1)+(2*9)+(1*9)=129
129 % 10 = 9
So 112881-99-9 is a valid CAS Registry Number.

Sterically Crowded Sulfonate Esters: Novel Leaving Groups with Hindered S-O Cleavage
Netscher, Thomas,Prinzbach, Horst
, p. 683 - 688 (2007/10/02)
Reagents and procedures for the preparation of tert-butyl sulfonate esters 2 and 2,2,2-trifluoro-1,1-diphenylethane sulfonate esters 3 (TDE-sulfonates) are described.In these new sulfonates, S-O-scission is reduced significantly by steric hindrance.
