107740-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 107740-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,7,7,4 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 107740-87:
(8*1)+(7*0)+(6*7)+(5*7)+(4*4)+(3*0)+(2*8)+(1*7)=124
124 % 10 = 4
So 107740-87-4 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.
