63257-86-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 63257-86-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,2,5 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 63257-86:
(7*6)+(6*3)+(5*2)+(4*5)+(3*7)+(2*8)+(1*6)=133
133 % 10 = 3
So 63257-86-3 is a valid CAS Registry Number.

Ruthenium-Catalyzed [2 + 2 + 2] Cycloaddition Reaction Forming 2-Aminopyridine Derivatives from α,ω-Diynes and Cyanamides

Ye, Fei,Haddad, Mansour,Ratovelomanana-Vidal, Virginie,Michelet, Véronique

supporting information, p. 1104 - 1107 (2017/03/14)

A novel, efficient, and mild synthetic route for the preparation of 2-aminopyridines via ruthenium-mediated [2 + 2 + 2] cycloaddition of α,ω-diynes and cyanamides has been developed. This atom-economical catalytic process demonstrated remarkable regioselectivities to access pyridine derivatives of high synthetic utility.
