Check Digit Verification of cas no

The CAS Registry Mumber 75257-03-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,2,5 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 75257-03:
(7*7)+(6*5)+(5*2)+(4*5)+(3*7)+(2*0)+(1*3)=133
133 % 10 = 3
So 75257-03-3 is a valid CAS Registry Number.

Comparison of cyclic and acyclic phosphites by selective phosphorylation. Synthesis of phosphatidylinositol 4-phosphate

Watanabe, Yutaka,Munetsugu, Hirofumi,Hayashi, Minoru

, p. 292 - 293 (2002)

To compare the synthetic utility of cyclic xylylene N,N-diethylphosphoramidite and its acyclic analog, dibenzyl ester, both phosphites derived from them with dipalmitoylglycerol were subjected to the selective phosphorylation at the OH-3 position in 1,2:4

A new approach to the synthesis of phosphatidic acids and their analogs

, p. 1011 - 1019 (2007/10/02)

The synthesis of phosphatidic acids, their monoamides and dialkyl esters, and thiophosphatidic acids was realized on the basis of the amidophosphites of 1,2-diacylglycerols and 1,2-isopropylideneglycerol.
