3115-55-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3115-55-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,1,1 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3115-55:
(6*3)+(5*1)+(4*1)+(3*5)+(2*5)+(1*5)=57
57 % 10 = 7
So 3115-55-7 is a valid CAS Registry Number.

Process for producing 6-aminopenicillanic acid or 7-aminocephalosporanic acid derivatives

-

, (2008/06/13)

A derivative of 6-aminopenicillanic acid or 7-aminocephalosporanic acid is produced by a process which comprises disulfidizing a 6-thioacylaminopenicillanic acid or 7-thioacylaminocephalosporanic acid compound to obtain a corresponding disulfide compound, and then solvolyzing the disulfide compound. The process is novel and industrially feasible for producing the amino compound, which is not accompanied by "reconversion reaction".
