562803-62-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 562803-62-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,6,2,8,0 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 562803-62:
(8*5)+(7*6)+(6*2)+(5*8)+(4*0)+(3*3)+(2*6)+(1*2)=157
157 % 10 = 7
So 562803-62-7 is a valid CAS Registry Number.

How robust is the hydrogen-bonded amide 'ladder' motif?
Aakeroey, Christer B.,Scott, Benjamin M. T.,Desper, John
, p. 2044 - 2051 (2008/03/30)
The well-known hydrogen-bonded ladder displayed by amides in the solid state, is readily disrupted and reduced to an R22(8) motif if a competitive hydrogen-bond acceptor is incorporated in the molecular structure of the amide. When a weaker hydrogen-bond
