74732-49-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74732-49-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,7,3 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74732-49:
(7*7)+(6*4)+(5*7)+(4*3)+(3*2)+(2*4)+(1*9)=143
143 % 10 = 3
So 74732-49-3 is a valid CAS Registry Number.

Stereospecific synthesis of secondary amines by the Mitsunobu reaction
Edwards,Stemerick,McCarthy
, p. 3417 - 3420 (2007/10/02)
A facile synthesis of secondary amines from alcohols is reported with N-methyltrifluoromethanesulfonamide (2) in the Mitsunobu reaction. The reaction was demonstrated to proceed with inversion of configuration and provided a convenient synthetic route to
