The CAS Registry Mumber 138964-05-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,9,6 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 138964-05:
(8*1)+(7*3)+(6*8)+(5*9)+(4*6)+(3*4)+(2*0)+(1*5)=163
163 % 10 = 3
So 138964-05-3 is a valid CAS Registry Number.

The First Synthesis of Aliphatic Sulfines from Thiono-esters

Lemarie, Margareth,Pham, Thi-Nhan,Metzner, Patrick

, p. 7411 - 7414 (1991)

Reaction of various thiono-esters with one equivalent of meta-chloroperoxybenzoic acid at 0 deg C in dichloromethane furnishes the corresponding sulfines, evidenced for the first time.These thiocarbonyl oxides are rather unstable at room temperature and give carboxylic esters, with loss of sulfur.The overall sequence provides an easy and quantitative C=S -> C=O transformation.
