Check Digit Verification of cas no

The CAS Registry Mumber 58808-68-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,8,0 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 58808-68:
(7*5)+(6*8)+(5*8)+(4*0)+(3*8)+(2*6)+(1*8)=167
167 % 10 = 7
So 58808-68-7 is a valid CAS Registry Number.

(: Z)-Selective anti-Markovnikov or Markovnikov thiol-yne-click reactions of an internal alkyne by amide hydrogen bond control

Pramanik, Milan,Choudhuri, Khokan,Chakraborty, Subhayan,Ghosh, Arindam,Mal, Prasenjit

supporting information, p. 2991 - 2994 (2020/03/19)

Herein, we show exclusive control of stereo and regioselective thiol-yne click (TYC) reactions of internal alkynes via amide hydrogen bond control. By exploiting appropriate hydrogen bonding interactions like N-H?S, N-H?N and C-H?O, either (Z)-selective anti-Markovnikov or Markovnikov products could be obtained for an internal alkyne, exclusively.
