Check Digit Verification of cas no

The CAS Registry Mumber 127940-92-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,4 and 0 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127940-92:
(8*1)+(7*2)+(6*7)+(5*9)+(4*4)+(3*0)+(2*9)+(1*2)=145
145 % 10 = 5
So 127940-92-5 is a valid CAS Registry Number.

Synthesis of Cyclic Amines and Allylic Sulfides by Phenylthio Migration of β-Hydroxy Sulfides

Coldham, Iain,Warren, Stuart

, p. 1637 - 1656 (2007/10/02)

Rearrangement of β-hydroxy sulfides proceeds stereospecifically with capture of the episulfonium ion by the nitrogen atom of an amide.Almost quantitative yields of substituted pyrrolidines are obtained using a sulfonamide as the intramolecular nucleophile

STEREOCONTROLLED AMIDOCYCLISATIONS WITH PHENYLTHIO MIGRATION

Coldham, Iain,Warren, Stuart

, p. 5937 - 5940 (2007/10/02)

Rearrangement of β-hydroxysulphides proceeds through an episulphonium ion which can be captured intramolecularly by the nitrogen atom of carbamates, ureas, or sulphonamides to give single diastereoisomers of pyrrolidines.With a free amine no capture takes
