Check Digit Verification of cas no

The CAS Registry Mumber 1133721-69-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,3,3,7,2 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1133721-69:
(9*1)+(8*1)+(7*3)+(6*3)+(5*7)+(4*2)+(3*1)+(2*6)+(1*9)=123
123 % 10 = 3
So 1133721-69-3 is a valid CAS Registry Number.

Access to a novel class of tetracyclic 1,4-benzodiazepin-5-ones starting from α-amino acids by Pd-catalyzed amination/1,3-dipolar cycloaddition as the key steps

A convenient procedure for the preparation of the novel class of tetracyclic imidazo[2,1-c]pyrazolo[1,5-α][1,4]benzodiazepine-5,8-diones is reported. The protocol uses cheap and easily accessible α-amino acids as chiral-pool starting materials and leads to products in an enantiopure form. An intramolecular palladium-catalyzed amination process to form the imidazole nucleus and an intramolecular 1,3-dipolar cycloaddition reaction to simultaneously achieve the pyrazole and 1,4-diazepine rings are the key steps.

Palladium-catalyzed domino carbopalladation/5-exo-allylic amination of α-amino allenamides: An efficient entry to enantiopure imidazolidinones

supporting information; experimental part, p. 1563 - 1566 (2009/08/07)

Allenamides of α-amino acids were converted into enantiopure 2-vinylimidazolidin-4-ones by a carbopalladation/exo-cyclization process. The products were obtained in 2.5:1-5.5:1 dr, with 94-99% ee. The palladium-catalyzed carbonylative cyclization of the s
