142407-58-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 142407-58-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,2,4,0 and 7 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 142407-58:
(8*1)+(7*4)+(6*2)+(5*4)+(4*0)+(3*7)+(2*5)+(1*8)=107
107 % 10 = 7
So 142407-58-7 is a valid CAS Registry Number.

A novel method for the alkoxylation of azetidin-2-ones at the 4-position
Kita,Shibata,Yoshida,Tohjo
, p. 1044 - 1046 (2007/10/02)
4-Sulfinylazetidin-2-ones were reacted with various types of tributyltin alkoxides in the presence of a catalytic amount of trimethylsilyltrifluoromethanesulfonate to give the corresponding trans-alkoxyazetidin-2-ones in high yields.
