Uses
Used in Pharmaceutical Industry:
α-[2-Chloro-1-hydroxy-1-(hydroxyMethyl)ethyl]-7-oxo-3-phenyl-4-oxa-2,6-diazabicyclo[3.2.0]hept-2-ene-6-acetic Acid DiphenylMethyl Ester is used as an intermediate in the synthesis of oxacephem derived beta-lactam antibiotics for their effectiveness against gram-positive bacteria. This application is due to its role in the development of new antibiotics that can combat resistant strains of bacteria, which is a significant concern in the medical field.
Check Digit Verification of cas no
The CAS Registry Mumber 68313-69-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,3,1 and 3 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 68313-69:
(7*6)+(6*8)+(5*3)+(4*1)+(3*3)+(2*6)+(1*9)=139
139 % 10 = 9
So 68313-69-9 is a valid CAS Registry Number.
