Check Digit Verification of cas no

The CAS Registry Mumber 224452-40-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,4,4,5 and 2 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 224452-40:
(8*2)+(7*2)+(6*4)+(5*4)+(4*5)+(3*2)+(2*4)+(1*0)=108
108 % 10 = 8
So 224452-40-8 is a valid CAS Registry Number.

Synthesis of new potential bis-intercalators based on chiral pyridine-2,6-dicarboxamides

Amr, Abd El-Galil,Abd El-Salam, Osama I.,Attia, Abd El-Hamid,Stibor, Ivan

, p. 288 - 298 (2007/10/03)

Potential bis-intercalating compounds N,N-dibenzylidene-N2,N2′-(pyridine-2,6-dicarbonyl)-d i(aminoacidhydrazides) 4a-4j, N,N′-substituted pyridine-2,6-bis(carbohydrazides) 5a-5d and N,N′-substituted N2N2′-bis(pyridine-2,6-dicarbonyl)di(aminoacidhydraz ides) 6a-6g, both racemic and optically active, can be easily synthesized from pyridine-2,6-bis(carbohydrazide), natural amino acids and aromatic aldehydes or anhydrides of aromatic ortho-dicarboxylic acids.
