94435-41-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 94435-41-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,4,3 and 5 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 94435-41:
(7*9)+(6*4)+(5*4)+(4*3)+(3*5)+(2*4)+(1*1)=143
143 % 10 = 3
So 94435-41-3 is a valid CAS Registry Number.

Hydrosulfonylation of Unactivated Alkenes by Visible Light Photoredox Catalysis

Wang, Juan-Juan,Yu, Wei

supporting information, p. 9236 - 9240 (2019/11/19)

The anti-Markovnikov hydrosulfonylation of unactivated alkenes with sodium sulfinates was realized via [Ir(dF(CF3)ppy)2(dtbbpy)]PF6-mediated visible light photoredox catalysis. The presence of an acid such as acetic acid is essential for the reaction to take place. A variety of unactivated alkenes can be transformed into sulfones with good yield and high regioselectivity using this reaction, which is proposed to proceed by a radical mechanism.
