Check Digit Verification of cas no

The CAS Registry Mumber 179009-37-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,9,0,0 and 9 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 179009-37:
(8*1)+(7*7)+(6*9)+(5*0)+(4*0)+(3*9)+(2*3)+(1*7)=151
151 % 10 = 1
So 179009-37-1 is a valid CAS Registry Number.

Study on the preparation of heteroaryl substituted enamines. A simple synthesis of heteroaryl substituted acetaldoximes from enamines

?opar, Anton,Stanovnik, Branko,Ti?ler, Miha

, p. 465 - 474 (2007/10/03)

A comparative study of the reactivity of methyl groups towards N,N-dimethylformamide dimethyl acetal and tert-butoxybis(dimethylamino)methane was carried out on methyl substituted six-membered nitrogen containing heterocycles 1 to give enamines 2, which were easily transformed to oximes by treating with hydroxylamine hydrochloride in methanol. Most of them were isolated as (E,Z)-oximes of heteroarylacetaldehyde (11), but 5-(1,2,4-triazinyl) substituted derivatives as (E,Z)-oximes of 2,5-dihydro-1,2,4-triazin-(Z)-5-ylideneacetaldehyde (11t, 11u, and 12). Oximes were finally transformed to the corresponding acetonitriles 16 and 3-(dimethylamino)acrylonitriles 17.
