Check Digit Verification of cas no
The CAS Registry Mumber 13519-90-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,1 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 13519-90:
(7*1)+(6*3)+(5*5)+(4*1)+(3*9)+(2*9)+(1*0)=99
99 % 10 = 9
So 13519-90-9 is a valid CAS Registry Number.

Photoinduced Copper(I)-Catalyzed Cyanation of Aromatic Halides at Room Temperature
Kim, Kicheol,Hong, Soon Hyeok
supporting information, p. 2345 - 2351 (2017/07/22)
The first photoinduced copper(I)-catalyzed cyanation of aromatic halides at room temperature has been developed. The sp2 cyanation reaction exhibits outstanding tolerance to functional groups including primary amines and carboxylic acids, and chemoselectivity to SN2-reactive alkyl chlorides. Mechanistic investigations indicate that the reaction occurs via a single-electron transfer (SET) between the aryl halide and an excited copper(I) cyanide catalytic intermediate. (Figure presented.).
