1432045-52-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1432045-52-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,2,0,4 and 5 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1432045-52:
(9*1)+(8*4)+(7*3)+(6*2)+(5*0)+(4*4)+(3*5)+(2*5)+(1*2)=117
117 % 10 = 7
So 1432045-52-7 is a valid CAS Registry Number.

Formal γ-alkynylation of ketones via Pd-catalyzed C-C cleavage
Ziadi, Asraa,Correa, Arkaitz,Martin, Ruben
supporting information, p. 4286 - 4288 (2013/05/23)
A formal γ-alkynylation of ketones via Pd-catalyzed C-C bond-cleavage is presented. The method allows for the coupling of tert-cyclobutanols and bromoacetylenes, giving access to versatile alkynes that are beyond reach otherwise.
