Check Digit Verification of cas no

The CAS Registry Mumber 31189-02-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,1,8 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 31189-02:
(7*3)+(6*1)+(5*1)+(4*8)+(3*9)+(2*0)+(1*2)=93
93 % 10 = 3
So 31189-02-3 is a valid CAS Registry Number.

Oxidative Alkoxylation/Dehydrogenation of Unactivated Cyclic Ketones with Simple Alcohols: Direct Route to α-Alkoxy Cycloenones

Yan, Yizhe,Li, Shaoqing,Wang, Jianyong

, p. 6474 - 6477 (2020/10/02)

An oxidative functionalization of cyclopentanones or cyclohexanones with simple alcohols was first demonstrated, affording a series of 2-alkoxycyclopent-2-en-1-ones or 2-alkoxycyclohex-2-en-1-ones in moderate to excellent yields. The reaction was involved in tandem iodization, substitution, oxidation and addition-elimination processes in one pot. This method is highly atom-economical and operationally simple.
