Check Digit Verification of cas no

The CAS Registry Mumber 66363-43-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,3,6 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 66363-43:
(7*6)+(6*6)+(5*3)+(4*6)+(3*3)+(2*4)+(1*3)=137
137 % 10 = 7
So 66363-43-7 is a valid CAS Registry Number.

Syntheses of (6S)-cephalosporins from 6-aminopenicillanic acid

Fekner, Tomasz,Baldwin, Jack E,Adlington, Robert M,Jones, Timothy W,Prout, C.Keith,Schofield, Christopher J

, p. 6053 - 6074 (2007/10/03)

Two practical routes to (6S,7S)-cephalosporins from 6-aminopenicillanic acid (6-APA) are described. In the first, 6-APA was converted to (2S,4S,5S,6S)-penicillin sulfoxide 49, which underwent Morin ring expansion to a protected (6S,7S)-cephem 50. In the s

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.
