Check Digit Verification of cas no

The CAS Registry Mumber 247153-82-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,1,5 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 247153-82:
(8*2)+(7*4)+(6*7)+(5*1)+(4*5)+(3*3)+(2*8)+(1*2)=138
138 % 10 = 8
So 247153-82-8 is a valid CAS Registry Number.

First synthesis and structural characterisation of a tertiary phosphine containing an azo linkage

Alder, Mark J.,Flower, Kevin R.,Pritchard, Robin G.

, p. 3571 - 3574 (1998)

Tertiary phosphines containing an azo linkage have been synthesised for the first time and one has been characterised by a single crystal X-ray diffraction study of its oxide.
