Check Digit Verification of cas no

The CAS Registry Mumber 64456-01-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,4,5 and 6 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 64456-01:
(7*6)+(6*4)+(5*4)+(4*5)+(3*6)+(2*0)+(1*1)=125
125 % 10 = 5
So 64456-01-5 is a valid CAS Registry Number.

SYNTHESES OF N,N,3- AND N,N,9-TRIALKYLADENINES BY ALKYLATION OF N,N-DIYLKYLADENINES

Itaya, Taisuke,Matsumoto, Hiroo,Ogawa, Kazuo

, p. 1920 - 1924 (2007/10/02)

Alkylation of N,B,N-dimethyl- (Ia) and N,N-diethyladenine (Ib) with methyl iodide, ethyl iodide, and benzyl bromide in N,N-dimethylacetamide in the presence of potassium carbonate gave the corresponding N,N,9-trialkyladenines (II) in 54-74percent yields, as well as minor amounts of N,N,3-trialkyladenines (III).The alkylation of I without base gave the latter compounds (III) in 76-90percent yields.Keywords - N,N,3-tryalkyladenines: N,N,9-trialkyladenines; regioselective N-alykaltion; N,N-dialkyladenines; isomer ratio.
