Check Digit Verification of cas no

The CAS Registry Mumber 1233705-47-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,3,7,0 and 5 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1233705-47:
(9*1)+(8*2)+(7*3)+(6*3)+(5*7)+(4*0)+(3*5)+(2*4)+(1*7)=129
129 % 10 = 9
So 1233705-47-9 is a valid CAS Registry Number.

Concise formal synthesis of porothramycins A and B via zincke pyridinium ring-opening/ring-closing cascade

Michels, Theo D.,Kier, Matthew J.,Kearney, Aaron M.,Vanderwal, Christopher D.

supporting information; experimental part, p. 3093 - 3095 (2010/08/20)

Short formal syntheses of the antitumor antibiotics porothramycins A and B from a commercially available ester of the unnatural amino acid 3-(3-pyridyl)alanine are presented. A rearrangement cascade that presumably involves a Zincke-type pyridinium ring-opening followed by cyclization of a pendant nucleophilic amide generates the salient pyrroline ring of the alkaloids.
