Check Digit Verification of cas no

The CAS Registry Mumber 65003-03-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,0,0 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 65003-03:
(7*6)+(6*5)+(5*0)+(4*0)+(3*3)+(2*0)+(1*3)=84
84 % 10 = 4
So 65003-03-4 is a valid CAS Registry Number.

Controlled Synthesis of β-Keto Sulfones and Vinyl Sulfones under Electrochemical Oxidation

Fang, Yang,Xu, Dongping,Yu, Yingliang,Tang, Rumeng,Dai, Shuaishuai,Wang, Zhenghua,Zhang, Wu

, (2022/04/09)

Selective sulfonylation and oxosulfonylation of alkenes with sulfinates have been developed via anodic oxidation in an undivided cell. The novel electrosynthetic method provided β-keto sulfones and vinyl sulfones with good to excellent yields in the absence of any transition metal catalyst and oxidants. Mechanism studies show that two different pathways involved in these two transformations.

Addition/elimination reactions of ethylsulfonyl pyridines: Stereoselective synthesis of vinylpyridine allylic alcohols

O'Neil, Gregory W.,Drake, Nathan D.,Storvick, Jennifer M.

supporting information, p. 715 - 717 (2013/02/23)

2-(Phenylsulfonyl)ethyl pyridines can be coupled with aldehydes leading directly to sulfone-eliminated vinylpyridine allylic alcohols. These products are obtained in good yield and with high levels of stereocontrol.
