Check Digit Verification of cas no

The CAS Registry Mumber 1254221-41-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,4,2,2 and 1 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1254221-41:
(9*1)+(8*2)+(7*5)+(6*4)+(5*2)+(4*2)+(3*1)+(2*4)+(1*1)=114
114 % 10 = 4
So 1254221-41-4 is a valid CAS Registry Number.

C-H bond functionalization in the synthesis of fused 1,2,3-triazoles

Panteleev, Jane,Geyer, Karolin,Aguilar-Aguilar, Angelica,Wang, Letian,Lautens, Mark

scheme or table, p. 5092 - 5095 (2011/02/22)

A highly modular approach to fused 1,2,3-triazoles has been developed featuring a one-pot procedure combining copper(I) catalyzed azide-alkyne cycloaddition and palladium-catalyzed C-H bond functionalization. A class of structurally unique heterocycles was synthesized in good yields.
