Check Digit Verification of cas no

The CAS Registry Mumber 1245644-68-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,5,6,4 and 4 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1245644-68:
(9*1)+(8*2)+(7*4)+(6*5)+(5*6)+(4*4)+(3*4)+(2*6)+(1*8)=161
161 % 10 = 1
So 1245644-68-1 is a valid CAS Registry Number.

TRIAZOLO PYRIDINES AS MODULATORS OF GAMMA-SECRETASE

-

Page/Page column 29, (2019/07/13)

The present invention relates to triazolo pyridines of formula (II) and their use as modulators of ?-secretase. In particular, the present invention relates to compounds which interfere with ?-secretase and/or its substrate and therefore modulate the form

Oxidative cyclization of 1-(pyridin-2-yl)guanidine derivatives: A synthesis of [1,2,4]triazolo[1,5-a]pyridin-2-amines and an unexpected synthesis of [1,2,4]triazolo[4,3-a]pyridin-3-amines

, p. 407 - 418 (2015/03/03)

Oxidative cyclization of 1-(pyridin-2-yl)guanidine derivatives using N-chlorosuccinimide and aqueous potassium carbonate has been investigated. Chlorination of 1-(5-nitropyridin-2-yl)guanidine by N-chlorosuccinimide in methanol followed by addition of aqueous potassium carbonate gave rise to cyclization and afforded 6-nitro-[1,2,4]triazolo[1,5-a]pyridin-2-amine in one-pot. In the course of studying the scope and limitation of the reaction, it was found that some of the examined 1-(pyridin-2-yl)guanidine derivatives gave not only the desired [1,2,4]triazolo[1,5-a]pyridin-2-amines but also unexpected [1,2,4]triazolo[4,3-a]pyridin-3-amine products. As plausible reaction mechanisms of this oxidative cyclization, diazirine formation and nitrene formation are presented.
