1280127-44-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1280127-44-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,0,1,2 and 7 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1280127-44:
(9*1)+(8*2)+(7*8)+(6*0)+(5*1)+(4*2)+(3*7)+(2*4)+(1*4)=127
127 % 10 = 7
So 1280127-44-7 is a valid CAS Registry Number.

Novel synthetic protocol toward pyrazolo[3,4-h]-[1,6]naphthyridines via Friedlander condensation of new 4-aminopyrazolo[3,4-b]pyridine-5-carbaldehyde with reactive α-methylene ketones

Jachak, Madhukar N.,Bagul, Sandeep M.,Kazi, Muddassar A.,Toche, Raghunath B.

, p. 295 - 300 (2011/06/10)

Novel pyrazolo[3,4-h][1,6]naphthyridine derivatives 6, 8, 9, 11, 13, and 15 have been synthesized by Friedlander condensation of new 4-amino-3-methyl-1- phenyl-1H-pyrazolo[3,4-b]pyridine-5-carbaldehyde (o-aminoaldehyde) 4 with active methylene ketones, such as symmetric acetone 5a, monoalkylketones 5b-k, unsymmetrical dialkyl ketones 7a-b, p-bromophenylacetonitrile 10, β-ketoester 12a, β-ketoamide 12b, or diethyl malonate 14, respectively.
