180468-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 180468-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,0,4,6 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 180468-23:
(8*1)+(7*8)+(6*0)+(5*4)+(4*6)+(3*8)+(2*2)+(1*3)=139
139 % 10 = 9
So 180468-23-9 is a valid CAS Registry Number.

Synthetic Approach to New Monocyclic β-Lactam Synthons
Mandic, Zorica,Kovacevic, Mice
, p. 661 - 667 (2007/10/03)
New cis and trans β-lactam synthons 4 and 9 have been prepared as suitable precursors for novel monocyclic β-lactam species. A new simple method have been found for the generation of 4 and 9 by hydrolysis of the 2-sulphonic acid methyl ester group and cle
