65252-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 65252-65-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,2,5 and 2 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 65252-65:
(7*6)+(6*5)+(5*2)+(4*5)+(3*2)+(2*6)+(1*5)=125
125 % 10 = 5
So 65252-65-5 is a valid CAS Registry Number.

Hetacillin (R)- and (S)-sulfoxides. Synthesis and structure-activity relationships
Gottestein,Kim,Shih,McGregor
, p. 240 - 242 (2007/10/10)
Hetacillin was oxidized with m-chloroperbenzoic acid to give the corresponding (R)- and (S)-sulfoxides. Ozonization of hetacillin not only oxidized the sulfide but caused unexpected oxidation of the imidazolidine ring to a 2H-imidazoline. The biological s
