143586-11-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143586-11-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,8 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143586-11:
(8*1)+(7*4)+(6*3)+(5*5)+(4*8)+(3*6)+(2*1)+(1*1)=132
132 % 10 = 2
So 143586-11-2 is a valid CAS Registry Number.

α-Oxosulfines: reactions with alkenes and alkynes
Still, Ian W. J.,Wilson, Donna Kaye T.
, p. 964 - 973 (2007/10/02)
Thiochroman-4-one 1,1-dioxide has been successfully converted into 3-sulfinylthiochroman-4-one 1,1-dioxide and the reactions of this α-oxosulfine with a series of alkenes have been carefully investigated.The α-oxosulfine was found to react as a Diels-Alde
