168134-87-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 168134-87-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,8,1,3 and 4 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 168134-87:
(8*1)+(7*6)+(6*8)+(5*1)+(4*3)+(3*4)+(2*8)+(1*7)=150
150 % 10 = 0
So 168134-87-0 is a valid CAS Registry Number.

The Synthesis of 4-Acetoxy-azetidin-2-ones as Key Intermediates for β-Lactams
Kehagia, Konstantina,Ugi, Ivar K.
, p. 9523 - 9530 (2007/10/02)
A short synthesis of a chiral precursor of a cephem derivative is described.Starting material is the inexpesive chiral-pool chemical aspartic acid.The central step in forming the β-lactam moiety is an Ugi reaction.
