Check Digit Verification of cas no

The CAS Registry Mumber 183797-20-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,7,9 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 183797-20:
(8*1)+(7*8)+(6*3)+(5*7)+(4*9)+(3*7)+(2*2)+(1*0)=178
178 % 10 = 8
So 183797-20-8 is a valid CAS Registry Number.

Organic phosphorus compounds 106.1 a 31P-NMR study of phosphinous-, phosphinic-, and thiophosphinic amides

Maier, Ludwig,Diel, Peter J.

, p. 273 - 300 (2007/10/03)

The synthesis, physical, chemical and spectroscopic properties of eight different types of phosphinous-, phosphinic-and thiophosphinic amides are reported. It is shown that the 31P-chem. shifts of tertiary amides are at lower magnetic field than that of secondary amides. As an exception, in the bis(tertiary butyl) series this trend is reversed.
