839673-20-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 839673-20-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,9,6,7 and 3 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 839673-20:
(8*8)+(7*3)+(6*9)+(5*6)+(4*7)+(3*3)+(2*2)+(1*0)=210
210 % 10 = 0
So 839673-20-0 is a valid CAS Registry Number.

The diastereoselective synthesis of quaternary substituted thioindolines from sulfur ylide intermediates
Nyong, Abijah M.,Rainier, Jon D.
, p. 746 - 748 (2005)
(Chemical Equation Presented) The Rh(II)-catalyzed coupling of chiral 2-thiopyranylindoles with vinyl diazoacetates results in the generation of indolines having quaternary substitution at C(3) in high diastereoselectivity.
