Check Digit Verification of cas no

The CAS Registry Mumber 126761-06-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,7,6 and 1 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 126761-06:
(8*1)+(7*2)+(6*6)+(5*7)+(4*6)+(3*1)+(2*0)+(1*6)=126
126 % 10 = 6
So 126761-06-6 is a valid CAS Registry Number.

Copper-catalysed Csp3-Csp cross-couplings between cyclobutanone oxime esters and terminal alkynes induced by visible light

Shi, Zhuangzhi,Wu, Yixiao,Yuan, Yu,Zhao, Binlin

, p. 4676 - 4679 (2020)

A novel transformation for the construction of Csp3-Csp bonds was achieved via a photo-induced copper-catalysed C-C bond cleavage. This approach was applied to prepare a series of highly functionalized alkynyl nitriles using readily available cyclobutanones and terminal alkynes. Mechanistic exploration showed that the in situ generated copper acetylide complex is an effective photosensitive catalyst to promote the C-C bond cleavage of cycloketoxime esters through a radical process.
