Check Digit Verification of cas no

The CAS Registry Mumber 100393-27-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,3,9 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 100393-27:
(8*1)+(7*0)+(6*0)+(5*3)+(4*9)+(3*3)+(2*2)+(1*7)=79
79 % 10 = 9
So 100393-27-9 is a valid CAS Registry Number.

Regiodivergent Copper Catalyzed Borocyanation of 1,3-Dienes

Jia, Tao,He, Qiong,Ruscoe, Rebecca E.,Pulis, Alexander P.,Procter, David J.

, p. 11305 - 11309 (2018)

Copper catalyzed multi-functionalization of unsaturated carbon-carbon bonds is a powerful tool for the generation of complex molecules. We report a regiodivergent process that allows a switch between 1,4-borocupration and 4,1-borocupration of 1,3-dienes upon a simple change in ligand. The subsequently generated allyl coppers are trapped in an electrophilic cyanation to selectively generate densely functionalized and synthetically versatile 1,2- or 4,3-borocyanation products.
