Check Digit Verification of cas no

The CAS Registry Mumber 1250258-34-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,0,2,5 and 8 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1250258-34:
(9*1)+(8*2)+(7*5)+(6*0)+(5*2)+(4*5)+(3*8)+(2*3)+(1*4)=124
124 % 10 = 4
So 1250258-34-4 is a valid CAS Registry Number.

Chemical synthesis with inductively heated copper flow reactors

Ceylan, Sascha,Klande, Tobias,Vogt, Carla,Friese, Carsten,Kirschning, Andreas

, p. 2009 - 2013 (2010)

Inductively heated copper wire inside a flow microreactor can serve as a source for a catalytic copper species that promotes 1,3-dipolar cycloadditions of alkynes with in situ formed azides to yield 1,2,3-triazoles. The same setup was used to carry out decarboxylations of 2-alkynoic acids and for the intramolecular C-O coupling of 2'-bromobiphenyl-2-carboxylic acid. Georg Thieme Verlag Stuttgart.
