Calculate Digit Verification of CAS Registry Number 699000-73:
(8*6)+(7*9)+(6*9)+(5*0)+(4*0)+(3*0)+(2*7)+(1*3)=182
182 % 10 = 2
So 699000-73-2 is a valid CAS Registry Number.

Synthesis of 1-phosphono-2-aza-1,3-dienes and scope of their aziridination
Vanderhoydonck, Bart,Stevens, Christian V.
, p. 722 - 734 (2007/10/03)
Several 1-phosphono-2-aza-1,3-dienes 14 and 1-aryl-1-phosphono-2-aza-1,3- dienes 15-17 were prepared by 1,4-dehydrochlorination of the corresponding diethyl [(2-chloro-1-alkylidene)amino]methylphosphonates 10-13. 1-Phosphono-2-aza-1,3-dienes 14 react smoo
