113518-40-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 113518-40-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 113518-40:
(8*1)+(7*1)+(6*3)+(5*5)+(4*1)+(3*8)+(2*4)+(1*0)=94
94 % 10 = 4
So 113518-40-4 is a valid CAS Registry Number.

TERT-BUTYL AND 2,2,2-TRIFLUORO-1,1-DIPHENYLETHANE-SULFONATES - HINDRANCE OF S-O-SCISSION IN SN2-SUBSTITUTION REACTIONS
Netscher, Thomas,Schwesinger, Reinhard
, p. 2115 - 2118 (2007/10/02)
By application of the tert-butyl sulfonates (4a) and the 2,2,2-trifluoro-1,1-diphenylethane (TDE-) sulfonates (4b) S-O-scission in SN2-substitution reactions can be drastically reduced.
