107668-26-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107668-26-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,6,6 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 107668-26:
(8*1)+(7*0)+(6*7)+(5*6)+(4*6)+(3*8)+(2*2)+(1*6)=138
138 % 10 = 8
So 107668-26-8 is a valid CAS Registry Number.

4-FLUOROAZETIDINONE DERIVATIVES FROM SECOPENICILLANATE SULPHONIUM TETRAFLUOROBORATES
Brennan, John,Hussain, Faiq H. S.,Virgili, Pedro
, p. 3199 - 3202 (2007/10/02)
Reaction of certain secopenicillanate esters with trimethyloxonium tetrafluoroborate yielded 4-fluoroazetidinone derivatives presumably via the intermediacy of secopenicillanate sulphonium tetrafluoroborate salts.
