143586-22-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143586-22-5 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, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 143586-22:
(8*1)+(7*4)+(6*3)+(5*5)+(4*8)+(3*6)+(2*2)+(1*2)=135
135 % 10 = 5
So 143586-22-5 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
