Check Digit Verification of cas no
The CAS Registry Mumber 55691-59-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,6,9 and 1 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 55691-59:
(7*5)+(6*5)+(5*6)+(4*9)+(3*1)+(2*5)+(1*9)=153
153 % 10 = 3
So 55691-59-3 is a valid CAS Registry Number.

Evidence for Cyclic Azaphosphiridine Oxide Intermediates in the Methoxide-induced Rearrangements of N-Alkyl α-Chlorophosphonamidates: Formation of Phosphoramidates as well as α-Aminophosphonates
Harger, Martin J. P.,Williams, Andrew
, p. 563 - 569 (2007/10/02)
The N-butyl α-chlorophosphonamidates RCHClP(O)(NBut)OMe (R=H, Me, or Ph) react with benzyltrimethylammonium methoxide in tetrahydrofuran-methanol to give two types of rearrangement product, the α-aminophosphonates ButNHCHRP(O)(OMe)2 and the phosphoramidates But(RCH2)NP(O)(OMe)2.For the phosphoramidates it seems necessary to postulate the formation of a cyclic azaphosphiridine oxide intermediate, and its subsequent ring-opening, by nucleophilic attack of methoxide at phosphorus, with cleavage of the P-C bond.The α-aminophosphonates are probably also derived from the azaphosphiridine oxide, by cleavage of the P-N bond.The observation that the proportion of the phosphoramidate (P-C cleavage) increases as R changes from Me to H to Ph accords with this picture, as does the apparent lack of any P-C bond cleavage in the rearrangement of Me2CClP(O)(NHR')OMe (R'=Me or But).
