Check Digit Verification of cas no

The CAS Registry Mumber 253439-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,3,4,3 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 253439-77:
(8*2)+(7*5)+(6*3)+(5*4)+(4*3)+(3*9)+(2*7)+(1*7)=149
149 % 10 = 9
So 253439-77-9 is a valid CAS Registry Number.

Bicyclic organophosphorus amides. Nucleophilic cleavage of 1-oxo-2,3- benzo-10-phenyl-4,7,10-triaza-1λ5-phosphabicyclo[5.3.0]decane and its p- anisyl analogues

He, Zhengjie,Modro, Tomasz A.

, p. 656 - 657 (1999)

Methanolysis of the title substrates leads to different products depending on the conditions: in the presence of HCl both P-N bonds are broken yielding a non-cyclic phosphonic diester while the MeO- ion reacts selectively breaking the P-N(Ar) bond and yielding a cyclic, seven-membered phosphonic amidoester.

Preparation of bicyclic phosphonic and phosphinic amides via N→C migration of phosphorus

He, Zhengjie,Modro, Tom A.

, p. 565 - 570 (2007/10/03)

New phosphonic diamides and phosphinic amides of the 4,7,10-triaza- 1λ5-phosphabicyclo[5.3.0]decane and 4,7,10-triaza-1λ5- phosphabicyclo[5.5.0]dodecane structures were prepared from bicyclic phosphoric triamides via the lithiation-induced N→C migration of phosphorus, followed by proton or haloalkane quenching.
