Check Digit Verification of cas no
The CAS Registry Mumber 144069-72-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,0,6 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 144069-72:
(8*1)+(7*4)+(6*4)+(5*0)+(4*6)+(3*9)+(2*7)+(1*2)=127
127 % 10 = 7
So 144069-72-7 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.
