Check Digit Verification of cas no

The CAS Registry Mumber 156181-20-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,1,8 and 1 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 156181-20:
(8*1)+(7*5)+(6*6)+(5*1)+(4*8)+(3*1)+(2*2)+(1*0)=123
123 % 10 = 3
So 156181-20-3 is a valid CAS Registry Number.

Regio- And Stereoselective Hydroiodination of Internal Alkynes with Ex Situ-Generated HI

Nozawa-Kumada, Kanako,Noguchi, Koto,Akada, Tomoya,Shigeno, Masanori,Kondo, Yoshinori

supporting information, p. 6659 - 6663 (2021/09/08)

Herein, we report an efficient and practical hydroiodination of internal alkynes using HI generated ex situ from the readily available triethylsilane and I2. This system offers high regio- and stereoselectivity to afford (E)-vinyl iodides in good yields under mild conditions. Furthermore, the hydroiodination reaction shows high functional group tolerance toward alkyl, methoxy, halogen, trifluoromethyl, cyano, ester, halomethyl, acid-sensitive silyl ether, and acetal moieties.
