Check Digit Verification of cas no

The CAS Registry Mumber 144205-56-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,2,0 and 5 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 144205-56:
(8*1)+(7*4)+(6*4)+(5*2)+(4*0)+(3*5)+(2*5)+(1*6)=101
101 % 10 = 1
So 144205-56-1 is a valid CAS Registry Number.

A change of mechanism of phosphoryl transfer by spatiotemporal effect

Sikder, Nirmala,Vaidyanathaswamy, R.

, p. 513 - 516 (2007/10/02)

New eight, nine and ten membered cyclic phosphates having transannularly placed nitrogen atom have been synthesized and subjected to hydrolysis in 20percent dioxane-water.The eight membered compounds undergo hydrolysis in the acid medium whereas the higher homologues are comparatively insensitive to change of pH.Nucleophilic participation of nitrogen in the eight membered and general acid-base catalysis in the nine and ten membered esters are found to be responsible for this reactivity difference.
