Check Digit Verification of cas no
The CAS Registry Mumber 27799-81-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,7,9 and 9 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 27799-81:
(7*2)+(6*7)+(5*7)+(4*9)+(3*9)+(2*8)+(1*1)=171
171 % 10 = 1
So 27799-81-1 is a valid CAS Registry Number.

Microwave-assisted benzyne-click chemistry: preparation of 1H-benzo[d][1,2,3]triazoles
Ankati, Haribabu,Biehl, Ed
supporting information; experimental part, p. 4677 - 4682 (2009/10/26)
The benzotriazoles were prepared by three-component and two-component microwave-assisted [3+2] cycloadditions of various azides to benzyne, 3-methoxybenzyne, and 4,5-difluorobenzyne. In the three-component reaction, the aryne is generated, in the presence of an azide prepared in situ, by the reaction of an o-(trimethylsilylaryl) triflate with either CsF or KF/18-Crown-6. However, in the two-component reactions, a freshly prepared azide is added to the reaction vessel prior to aryne generation. Good to excellent yields of benzotriazoles were obtained in 15-20 min when the microwave-assisted reactions were carried out at 125 °C. These reaction times are significantly faster than similar reactions carried out using conventional heating.
