783356-71-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 783356-71-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,8,3,3,5 and 6 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 783356-71:
(8*7)+(7*8)+(6*3)+(5*3)+(4*5)+(3*6)+(2*7)+(1*1)=198
198 % 10 = 8
So 783356-71-8 is a valid CAS Registry Number.

A visible-light photocatalytic thiolation of aryl, heteroaryl and vinyl iodides

supporting information, p. 1543 - 1551 (2018/03/08)

The general catalytic synthesis of aryl and vinyl thioethers from readily available halides remains a challenge. Herein we report a unified method for the thiolation of aryl and vinyl iodides with dialkyl disulfides using visible light photoredox catalysis. A range of thioether products bearing diverse functional groups can be accessed in high yield and with excellent chemoselectivity. We demonstrate the versatility of this method through the expedient synthesis of a family of thioether-rich natural products. A detailed investigation of the photocatalytic mechanism is presented from both steady-state and time-resolved luminescent quenching as well as transient absorption spectroscopy experiments.
