80734-22-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 80734-22-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,0,7,3 and 4 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 80734-22:
(7*8)+(6*0)+(5*7)+(4*3)+(3*4)+(2*2)+(1*2)=121
121 % 10 = 1
So 80734-22-1 is a valid CAS Registry Number.

Synthesis and antibacterial activity of 3-acylamino-3-methoxy-2-azetidinone-1-sulfonic acid derivatives
Matsuo,Masuya,Sugawara,Kawano,Noguchi,Ochiai
, p. 2200 - 2208 (2007/10/02)
As a key intermediate for the synthesis of sulfazecin derivatives, 3-amino-3-methoxy-2-azetidinone (24 or 26) was synthesized from penicillins, and various new compounds, including sulfazecin, were synthesized by acylation and sulfonation of 24 or 26. Som
