Check Digit Verification of cas no

The CAS Registry Mumber 205651-77-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,5,6,5 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 205651-77:
(8*2)+(7*0)+(6*5)+(5*6)+(4*5)+(3*1)+(2*7)+(1*7)=120
120 % 10 = 0
So 205651-77-0 is a valid CAS Registry Number.

An efficient synthesis of 3-phosphorylated 4(1H)-pyridones and 4-chloropyridines from β-enaminophosphonates

Palacios, Francisco,De Retana, Ana Ma Ochoa,Oyarzabal, Julen

, p. 517 - 524 (2007/10/03)

An easy and efficient synthesis of 4(1H)-pyridones (1) substituted with a phosphate group in the 3-position is described. The key step is an addition of β-enaminophosphonates (2) to acylketene (3) generated either from diketene (4) or from the "diketene-a
