Check Digit Verification of cas no

The CAS Registry Mumber 66205-44-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,2,0 and 5 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 66205-44:
(7*6)+(6*6)+(5*2)+(4*0)+(3*5)+(2*4)+(1*4)=115
115 % 10 = 5
So 66205-44-5 is a valid CAS Registry Number.

Tert-Butoxide-Mediated Arylation of 2-Substituted Cyanoacetates with Diaryliodonium Salts

Qian, Xiaofei,Han, Jianwei,Wang, Limin

, p. 940 - 946 (2016)

A transition metal-free direct arylation of 2-substituted cyanoacetates with diaryliodonium salts was developed. With this approach, a wide range of α-tolunitrile derivatives has been synthesized in good to excellent yields of 45-92%. Furthermore, the practicability of this approach is further manifested in the synthesis of a related bioactive agent of glutarimide.
