Check Digit Verification of cas no

The CAS Registry Mumber 23768-21-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,3,7,6 and 8 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 23768-21:
(7*2)+(6*3)+(5*7)+(4*6)+(3*8)+(2*2)+(1*1)=120
120 % 10 = 0
So 23768-21-0 is a valid CAS Registry Number.

Isocyanide-Induced Activation of Copper Sulfate: Direct Access to Functionalized Heteroarene Sulfonic Esters

Hong, Xiaohu,Tan, Qitao,Liu, Bingxin,Xu, Bin

, p. 3961 - 3965 (2017)

A novel and direct approach to alkyl/aryl heteroarene sulfonic esters using copper sulfate as the environmentally benign inorganic sulfonation reagent was first realized with the aid of isocyanide. A variety of heterocycles reacted to afford the corresponding sulfonic esters through C?H functionalization. In this transformation, the otherwise inert copper sulfate was unusually activated by an isocyanide and employed as the source of the sulfonic substituents in an unprecedented fashion. The findings suggest that an appropriate activator may liberate the chemical activities of some relatively inert inorganic salts for organic synthesis.
