1057717-25-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1057717-25-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,5,7,7,1 and 7 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1057717-25:
(9*1)+(8*0)+(7*5)+(6*7)+(5*7)+(4*1)+(3*7)+(2*2)+(1*5)=155
155 % 10 = 5
So 1057717-25-5 is a valid CAS Registry Number.

Seeliger, Florian,Mayr, Herbert
experimental part, p. 3052 - 3058 (2009/02/03)
Kinetics of the reactions of four benzenesulfonyl-stabilized carbanions (1a-d)- with reference electrophiles (quinone methides 2 and diarylcarbenium ions 3) have been determined in dimethyl sulfoxide solution at 20 °C in order to derive the rea
