Check Digit Verification of cas no

The CAS Registry Mumber 219598-46-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,9,5,9 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 219598-46:
(8*2)+(7*1)+(6*9)+(5*5)+(4*9)+(3*8)+(2*4)+(1*6)=176
176 % 10 = 6
So 219598-46-6 is a valid CAS Registry Number.

Synthesis of aryl-substituted triamidoamine ligands and molybdenum(IV) complexes that contain them

Greco, George E.,Popa, Alexandru I.,Schrock, Richard R.

, p. 5591 - 5593 (1998)

Compounds of the type [(ArNHCH2CH2)3N] (Ar = phenyl (H3[1a]), 4-fluorophenyl (H3[1b]), 4-tertbutylphenyl (H3[1c]), 3,5-dimethylphenyl (H3[1d]), 2-methylphenyl (H3[1e]), and mesityl (H3[1f])) have been synthesized by the Pd-catalyzed coupling of (H2NCH2CH2)3N with aryl bromides. Molybdenum methyl complexes containing [1a-d]3- can be prepared by adding 4 equiv of methyllithium to a mixture of the ligand and MoCl4(THF)2; the corresponding chloride complexes are obtained upon addition of 2,6-lutidinium chloride to the methyl complexes. .
