Check Digit Verification of cas no

The CAS Registry Mumber 1221970-98-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,1,9,7 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1221970-98:
(9*1)+(8*2)+(7*2)+(6*1)+(5*9)+(4*7)+(3*0)+(2*9)+(1*8)=144
144 % 10 = 4
So 1221970-98-4 is a valid CAS Registry Number.

A cobalt-catalyzed sulfonate/copper exchange for the preparation of highly functionalized electron-deficient aryl copper reagents

Rohbogner, Christoph J.,Diene, Coura R.,Korn, Tobias J.,Knochel, Paul

supporting information; experimental part, p. 1874 - 1877 (2010/06/16)

(Chemical Equation Presentation) Organocopper reagents from phenols: A new cobalt-catalyzed aryl sulfonate/ copper exchange reaction allows the synthesis of highly functionalized aryl copper reagents from sulfonates bearing elec-tron-deficient substituents under mild conditions (25-45 °C, 1-6 h; see example). Sensitive functional groups, such as aldehydes, esters, and nitriles, are welltolerated.
