Check Digit Verification of cas no

The CAS Registry Mumber 1123496-72-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,2,3,4,9 and 6 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1123496-72:
(9*1)+(8*1)+(7*2)+(6*3)+(5*4)+(4*9)+(3*6)+(2*7)+(1*2)=139
139 % 10 = 9
So 1123496-72-9 is a valid CAS Registry Number.

Syntheses of substituted 8-(aminobenzyl)dinaphthodioxaphosphocine 8-oxides

Babu, M. F. Stephen,Babu, B. Hari,Reddy, K. R. Kishore Kumar,Raju, C. Naga,Reddy, C. Suresh

, p. 1336 - 1341 (2007)

Substituted (8-aminobenzyl)dinaphthodioxaphosphocine 8-oxides were prepared in a two-step process. The first step of the reaction is one-pot synthesis of α-aminophosphonates by the reaction of aldehydes, amines, and trialkyl phosphite in the presence of ceric ammonium nitrate. The second step is cyclization of α-aminophosphonates with bis(2-hydroxy-1-naphthyl)methane in the presence of a catalytic amount of p toluenesulphonic acid under reflux conditions. Their structures were established by elemental analyses, IR, 1H, 13C, 31P NMR, and mass spectral data.
