Check Digit Verification of cas no

The CAS Registry Mumber 144776-54-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,7,7 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 144776-54:
(8*1)+(7*4)+(6*4)+(5*7)+(4*7)+(3*6)+(2*5)+(1*4)=155
155 % 10 = 5
So 144776-54-5 is a valid CAS Registry Number.

Metaphosphate intermediates from fluoroaromatic precursors

Chambers, Richard D.,Dillon, Keith B.,Straw, Thomas A.

, p. 385 - 388 (1992)

Flow pyrolysis of some 2-aryloxy-1,3,2-dioxaphospholanes with ortho-CF3 or F substituents, either alone or in the presence of methanol, has provided evidence for the formation of methaphosphates as intermediates; these highly reactive species then undergo further reaction, depending on the nature of the substituent.Mass spectrometric studies of the starting materials have also suggested the elimination of ethylene and the formation of methaphosphates to a limited extent.
