96828-58-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 96828-58-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,6,8,2 and 8 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 96828-58:
(7*9)+(6*6)+(5*8)+(4*2)+(3*8)+(2*5)+(1*8)=189
189 % 10 = 9
So 96828-58-9 is a valid CAS Registry Number.

The thioformimidate 4, which may be obtained by S-methylation of 5 reacts with chloroacetyl chloride/triethylamine to yield the trans-2-azetidinone 7. 7 is dehalogenated to 8.Removal of the protective group leads to 9, which undergoes ring closure by the
