Check Digit Verification of cas no
The CAS Registry Mumber 155373-46-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,3,7 and 3 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 155373-46:
(8*1)+(7*5)+(6*5)+(5*3)+(4*7)+(3*3)+(2*4)+(1*6)=139
139 % 10 = 9
So 155373-46-9 is a valid CAS Registry Number.

A new synthetic route to macrocycles: Synthesis of large ring enaminolactones
Jourdain,Pommelet
, p. 1545 - 1548 (2007/10/02)
Macrocyclic enaminolactones 5 are prepared in three steps from commercially available chloroalcohols 1. The cyclization step is performed by intramolecular nucleophilic addition of the hydroxy group to an aminomethyleneketene generated by thermolysis.
