Check Digit Verification of cas no
The CAS Registry Mumber 13719-97-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,1 and 9 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 13719-97:
(7*1)+(6*3)+(5*7)+(4*1)+(3*9)+(2*9)+(1*7)=116
116 % 10 = 6
So 13719-97-6 is a valid CAS Registry Number.

Electrophilic substitution of asymmetrically distorted benzenes within triptycene derivatives
Miura, Masahiro,Nishii, Yuji,Ueno, Keisuke
, p. 3552 - 3556 (2021)
Herein, we disclose a unique directing effect of 9-substituted triptycenes in electrophilic substitution to achieve the regioselective functionalization of the triptycene core. The Hirshfeld population analysis was adopted to predict the selectivity in el
