Check Digit Verification of cas no
The CAS Registry Mumber 1678-56-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,7 and 8 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1678-56:
(6*1)+(5*6)+(4*7)+(3*8)+(2*5)+(1*6)=104
104 % 10 = 4
So 1678-56-4 is a valid CAS Registry Number.

The partial aminolysis of (NPF2)3,4

Unlike the reactions of (NPCl2)3,4 with simple amines, the fluorocyclophosphazenes, (NPF2)3,4, react with methylamine, n-butylamine, or dimethylamine with replacement of only one fluorine atom per phosphorus to yield products such as N4P4F5(NHMe)3, N4P4F4(NHMe)4, N4P4F5(NHC4H9) 3, N4P4F5(NMe2)3, N4P4F4(NMe2)4, N3P3F4(NHMe)2, N3P3-F4(NHC4H9) 2, or N3P3F4(NMe2)2. This behavior cannot be ascribed to steric effects because nucleophiles such as CF3CH2ONa, C6H5ONa, and (CH3)2NLi readily replace all the fluorine atoms. The results are more compatible with an explanation based on the poor leaving-group ability of fluoride combined with the low nucleophilicity of the free amines, compared with the higher leaving-group ability of chloride and the high nucleophilicity of alkoxides, aryl oxides, or metal amides.
