(7*9)+(6*9)+(5*4)+(4*9)+(3*8)+(2*8)+(1*7)=220
220 % 10 = 0
So 99498-87-0 is a valid CAS Registry Number.

STUDIES OF DITHIIRANES AND THIOSULFINES AS REACTIVE INTERMEDIATES

Senning, Alexander,Hansen, Holger C.,Abdel-Megeed, Mohamed F.,Mazurkiewicz, Witold,Jensen, Birgit

, p. 739 - 746 (2007/10/02)

Indirect, but compelling evidence for the intermediacy of dithiiranes 1 and thiosulfines 2 has been found by us and is also provided by literature data.The intriguing dithiirane -> dithioester rearrangement as well as most of the interrelations and conversions postulated in Scheme 1 have been demonstrated experimentally.In a number of cases acetyl α-chloroalkyl disulfides 16 (X=Cl, Y=COCH3) are useful starting materials for the synthesis of thioamides such as 40.
