Check Digit Verification of cas no

The CAS Registry Mumber 217493-45-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,7,4,9 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 217493-45:
(8*2)+(7*1)+(6*7)+(5*4)+(4*9)+(3*3)+(2*4)+(1*5)=143
143 % 10 = 3
So 217493-45-3 is a valid CAS Registry Number.

A synthetic approach towards the aromatic macrocyclic core of diazonamide a based on sp2-sp2 coupling protocols

Boto, Alicia,Ling, Matthew,Meek, Graham,Pattenden, Gerald

, p. 8167 - 8170 (1998)

The scope for a range of sp2-sp2 coupling protocols to elaborate the phenyl-indole, indoleoxazole, oxazole-oxazole, and quaternary carbon units in the marine natural product diazonamide A 1 are described, leading to the synthesis of the benzofuran oxazoles 11a and 18, the benzofuran/biphenyl/indole 16, and the indole-bis-oxazole 25.
