Check Digit Verification of cas no

The CAS Registry Mumber 4420-99-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,2 and 0 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4420-99:
(6*4)+(5*4)+(4*2)+(3*0)+(2*9)+(1*9)=79
79 % 10 = 9
So 4420-99-9 is a valid CAS Registry Number.

PHOSPHORORGANISCHE VERBINDUNGEN 102. TERTIAERE PHOSPHINE MIT o-DIALKYLAMINOPHENYL- UND ORTHO-DIALKYLAMINOBENZYLGRUPPEN

Horner, L.,Simons, G.

, p. 165 - 176 (2007/10/02)

N,N-dialkylarylamines and N,N-dialkylbenzylamines are lithiated with n-butyllithium (n-BuLi) under the assistance of tetramethylethylenediamine (TMEDA) in the ortho-position.According the Eqs. (1) and (4) triarylphosphines (30-50percent) are obtained. 1-(N,N-dimethylamino)-naphthalene and N,N-dimethyl-1-(1-naphthyl)-ethylamine 18 are lithiated in the 8-position.In N,N-dimethyl-1-(2-naphthyl)-ethylamine 19 the 1- and 3-position is lithiated in nearly equal amount.Experiments to introduce lithium twice into the model compounds 28-30 are without success.
