Check Digit Verification of cas no

The CAS Registry Mumber 1605332-33-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,5,3,3 and 2 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1605332-33:
(9*1)+(8*6)+(7*0)+(6*5)+(5*3)+(4*3)+(3*2)+(2*3)+(1*3)=129
129 % 10 = 9
So 1605332-33-9 is a valid CAS Registry Number.

Synthesis and structural characterization of pyrrole heterocyclic systems bearing amino acid units: Novel pyrrol-3-ones, pyrrolo[1,2-a][3,1]benzoxazines, and pyrrolo[2,1-b][1,3]oxazoles

Koca, Irfan,Sacmaci, Mustafa,Yilmaz, Filiz,Uengoerena, Sevket Hakan

, p. 212 - 218 (2014/02/14)

Furan-3-one derivatives 1 were converted into 2-hydroxy-pyrrole-3-ones 4 by reacting with various α- and β-amino acids. In contrast, the reaction of furan-3-ones and 1-aminocyclobutanecarboxylic acid afforded spiro-pyrrolo[2,1-b][1,3]oxazoles 5 via the pyrrole-3-one intermediate under the same reaction conditions. Some of 2-hydroxy-pyrrole-3-ones 3 derived from anthranilic acids were transformed to pyrrolo[1,2-a][3,1]benzoxazines via intramolecular esterification.
