Check Digit Verification of cas no

The CAS Registry Mumber 1618650-52-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,8,6,5 and 0 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1618650-52:
(9*1)+(8*6)+(7*1)+(6*8)+(5*6)+(4*5)+(3*0)+(2*5)+(1*2)=174
174 % 10 = 4
So 1618650-52-4 is a valid CAS Registry Number.

A new synthetic approach to 6-unsubstituted phenanthridine and phenanthridine-like compounds under mild and metal-free conditions

, p. 5077 - 5081 (2014/07/08)

A new and mild synthetic approach for the synthesis of 6-unsubstituted phenanthridine and phenanthridine-like compounds under metal-free conditions at room temperature has been developed. The strategy involved a tandem azide rearrangement/intramolecular annulation and oxidation reactions of biarylmethyl azide precursors to obtain the desired products in up to 99% yields with high regioselectivity.
