Check Digit Verification of cas no

The CAS Registry Mumber 1618698-35-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,1,8,6,9 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1618698-35:
(9*1)+(8*6)+(7*1)+(6*8)+(5*6)+(4*9)+(3*8)+(2*3)+(1*5)=213
213 % 10 = 3
So 1618698-35-3 is a valid CAS Registry Number.

Straightforward access to hexahydropyrrolo[2,3-b]indole core by a regioselective c3-azo coupling reaction of arenediazonium compounds with tryptamines

Stephens, David E.,Larionov, Oleg V.

, p. 3662 - 3670 (2014)

A base-mediated regioselective electrophilic addition of arenediazonium salts at the C3-position of tryptamines followed by cyclization provides an efficient entry to C3-nitrogenated hexahydropyrrolo[2,3-b]indoles (HPIs) that can subsequently be transformed into 3-arylhexahydropyrrolo[2,3-b]indoles and other HPI derivatives. The reaction is the first example of a 1,2-diamination that utilizes easily accessible arenediazonium salts as nitrogenous electrophiles. Copyright
