Check Digit Verification of cas no

The CAS Registry Mumber 1202357-35-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,0,2,3,5 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1202357-35:
(9*1)+(8*2)+(7*0)+(6*2)+(5*3)+(4*5)+(3*7)+(2*3)+(1*5)=104
104 % 10 = 4
So 1202357-35-4 is a valid CAS Registry Number.

Synthesis and reactivity of enantiomerically enriched thiiranium ions

Denmark, Scott E.,Vogler, Thomas

supporting information; experimental part, p. 11737 - 11745 (2010/06/12)

Enantiomerically enriched thiiranium ion 5 has been prepared by silverassisted ionization of chloro sulfide 4 at -20°C. This thiiranium ion is configurationally stable in solution up to room temperature as demonstrated by the stereospecific capture of the ion by various oxygen- and nitrogen-based nucleophiles. Both isolated olefins and weak Lewis bases can promote the racemization of 5 but these processes can also be suppressed at low temperature. Capture of 5 by methanol is faster than the racemization processes.
