Synthesis Reference(s)
Journal of the American Chemical Society, 74, p. 4005, 1952 DOI: 10.1021/ja01136a010
Purification Methods
If IR is free of OH bands then fractionally distil it; otherwise dilute the thio-ester with dry Et2O, wash with 5% KOH and H2O, dry over MgSO4 and fractionate it through an efficient column [Hauptschein et al. J Am Chem Soc 74 4005 1952]. [Beilstein 2 IV 567.] Powerful obnoxious odour.
Check Digit Verification of cas no
The CAS Registry Mumber 383-64-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,8 and 3 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 383-64:
(5*3)+(4*8)+(3*3)+(2*6)+(1*4)=72
72 % 10 = 2
So 383-64-2 is a valid CAS Registry Number.
