Check Digit Verification of cas no

The CAS Registry Mumber 1228504-83-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,8,5,0 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1228504-83:
(9*1)+(8*2)+(7*2)+(6*8)+(5*5)+(4*0)+(3*4)+(2*8)+(1*3)=143
143 % 10 = 3
So 1228504-83-3 is a valid CAS Registry Number.

Combined InCl3- and amine-catalyzed intramolecular addition of α-disubstituted aldehydes onto unactivated alkynes

Montaignac, Benjamin,Vitale, Maxime R.,Michelet, Veronique,Ratovelomanana-Vidal, Virginie

, p. 2582 - 2585 (2010)

The combination of enamine-type catalysis to the indium-catalyzed activation of alkynes allows the efficient preparation of functionalized cyclopentanes bearing a quaternary stereogenic center. A broad range of formylalkynyl derivatives has been prepared.
