Check Digit Verification of cas no

The CAS Registry Mumber 1245550-45-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,5,5 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1245550-45:
(9*1)+(8*2)+(7*4)+(6*5)+(5*5)+(4*5)+(3*0)+(2*4)+(1*5)=141
141 % 10 = 1
So 1245550-45-1 is a valid CAS Registry Number.

One-pot synthesis of imidazole-4-carboxylates by microwave-assisted 1,5-electrocyclization of azavinyl azomethine ylides

experimental part, p. 4312 - 4320 (2010/10/21)

Diversely functionalized imidazole-4-carboxylates were synthesized by microwave-assisted 1,5-eletrocyclization of 1,2diaza-l,3-diene-derived azavinyl azomethine ylides. 1,2-Diaza-1,3-dienes were treated with primary aliphatic or aromatic amines and subjected to microwave irradiation in the presence of aldehydes. 3-Alkyl- and 3-arylimidazole-4-carboxylates were prepared in good yields through a one-pot multicomponent procedure. Modulation of the substituents at C-2, N-3, and C-5 was possible, and 2-unsubstituted imidazoles were obtained when paraformaldehyde was used.
