Check Digit Verification of cas no

The CAS Registry Mumber 858026-24-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,8,0,2 and 6 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 858026-24:
(8*8)+(7*5)+(6*8)+(5*0)+(4*2)+(3*6)+(2*2)+(1*4)=181
181 % 10 = 1
So 858026-24-1 is a valid CAS Registry Number.

Enantioposition-selective copper-catalyzed azide-alkyne cycloaddition for construction of chiral biaryl derivatives

Osako, Takao,Uozumi, Yasuhiro

, p. 5866 - 5869 (2014)

A highly enantioposition-selective copper-catalyzed azide-alkyne cycloaddition (CuAAC) of dialkynes bearing prochiral biaryls has been developed for the construction of 1,2,3-triazoles bearing axially chiral biaryl groups in up to 76% yield and up to 99% ee.
