Check Digit Verification of cas no

The CAS Registry Mumber 83412-77-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,1 and 2 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 83412-77:
(7*8)+(6*3)+(5*4)+(4*1)+(3*2)+(2*7)+(1*7)=125
125 % 10 = 5
So 83412-77-5 is a valid CAS Registry Number.

Reactions of N-Heteroarylformamide Oximes and N-Heteroarylacetamide Oximes with N,N-Dimethylformamide Dimethyl Acetal. Synthesis of 2-Methyl-s-triazoloazines and N-Methylcyanoaminoazines

Stanovnik, Branko,Stimac, Anton,Tisler, Miha,Vercek, Bojan

, p. 577 - 583 (2007/10/02)

N-Heteroarylformamide oximes 3 (R = H) were converted with N,N-dimethylformamide dimethyl acetal (DMFDMA) into N-heteroaryl-N-methylcyanoamino compounds 5, as the main products.In some instances N-heteroarylcyanoamino compounds 4, cyanoimino compounds 7, and some other products, such as 9 and 10 were also formed.On the other hand, N-heteroarylacetamide oximes 3 (R = CH3) were cyclized under the same reaction conditions into 2-methyl-s-triazoloazines (6).N-Heteroarylacetamide O-methyl oximes 11 and 12 were prepared from the corresponding acetamidines 2 (R = CH3) and O-methylhydroxylamine.
