Check Digit Verification of cas no

The CAS Registry Mumber 1604835-55-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,4,8,3 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1604835-55:
(9*1)+(8*6)+(7*0)+(6*4)+(5*8)+(4*3)+(3*5)+(2*5)+(1*5)=163
163 % 10 = 3
So 1604835-55-3 is a valid CAS Registry Number.

Regioselective synthesis of diversely substituted diazoninones through a post-Ugi gold-catalyzed intramolecular hydroarylation process

Li, Zhenghua,Kumar, Amit,Vachhani, Dipak D.,Sharma, Sunil K.,Parmar, Virinder S.,Van Der Eycken, Erik V.

, p. 2084 - 2091 (2014/04/17)

A highly efficient approach for the regioselective construction of fused nine-membered rings (diazoninone framework) was developed by employing sequential Ugi and gold-catalyzed intramolecular hydroarylation reactions. The scope of this intramolecular cyc
