Check Digit Verification of cas no

The CAS Registry Mumber 109469-92-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,4,6 and 9 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 109469-92:
(8*1)+(7*0)+(6*9)+(5*4)+(4*6)+(3*9)+(2*9)+(1*2)=153
153 % 10 = 3
So 109469-92-3 is a valid CAS Registry Number.

Assembly of substituted phenanthridines via a cascade palladium-catalyzed coupling reaction, deprotection and intramolecular cyclization

Ge, Jun,Wang, Xiaojian,Liu, Tianqi,Shi, Zeyu,Xiao, Qiong,Yin, Dali

, p. 19571 - 19575 (2016)

The discovery and development of a general method for the one-pot synthesis of substituted phenanthridines is presented. In the presence of Pd(PPh3)4, accessible precursors undergo a Suzuki cross-coupling reaction with 2-(Boc-amino)benzeneboronic acid pinacol ester and then spontaneously undergo deprotection and intramolecular condensation to form the corresponding phenanthridines in one step. This reaction has a wide range of substrates with various functional groups, and the corresponding products have been obtained in good yields.
