Check Digit Verification of cas no

The CAS Registry Mumber 1216947-32-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,6,9,4 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1216947-32:
(9*1)+(8*2)+(7*1)+(6*6)+(5*9)+(4*4)+(3*7)+(2*3)+(1*2)=158
158 % 10 = 8
So 1216947-32-8 is a valid CAS Registry Number.

Tricyclic alkaloid core structures assembled by a cyclotrimerizationcoupled intramolecular nucleophilic substitution reaction

Mclver, Andrew L.,Deiters, Alexander

, p. 1288 - 1291 (2010)

Chemical Equation Presented A facile approach to tricyclic alkaloid core structures was developed by sequencing a pyrldine-forming [2 + 2 + 2] cyclotrimerization reaction with an intramolecular nucleophilic substitution. This methodology enabled the facile assembly of the spiroindolinone framework of citrinadins A and B, and cyclopiamine B.
