Check Digit Verification of cas no

The CAS Registry Mumber 17269-79-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,2,6 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17269-79:
(7*1)+(6*7)+(5*2)+(4*6)+(3*9)+(2*7)+(1*9)=133
133 % 10 = 3
So 17269-79-3 is a valid CAS Registry Number.

Concise and practical synthesis of 4-O-methylhonokiol was achieved in 34% overall yield. The key features of our synthesis include chemoselective ortho-mono bromination of phenol as well as biaryl formation via Suzuki-Miyaura cross-coupling, in which bromophenol was reacted with potassium aryltrifluoroborate using Pd(OAc)2 and RuPhos under microwave conditions.
