Check Digit Verification of cas no

The CAS Registry Mumber 1393444-73-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,3,4,4 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1393444-73:
(9*1)+(8*3)+(7*9)+(6*3)+(5*4)+(4*4)+(3*4)+(2*7)+(1*3)=179
179 % 10 = 9
So 1393444-73-9 is a valid CAS Registry Number.

Nickel-catalyzed arylation of heteroaryl-containing diarylmethanes: Exceptional reactivity of the Ni(NIXANTPHOS)-based catalyst

Cao, Xinyu,Sha, Sheng-Chun,Li, Minyan,Kim, Byeong-Seon,Morgan, Catherine,Huang, Rudan,Yang, Xiaodong,Walsh, Patrick J.

, p. 611 - 618 (2015/12/26)

Nickel(0)-catalyzed cross-coupling of heteroaryl-containing diarylmethanes with both aryl bromides and chlorides has been achieved. The success of this reaction relies on the introduction of a unique nickel/NIXANTPHOS-based catalyst system, which provides a direct route to triarylmethanes from heteroaryl-containing diarylmethanes. Reactivity studies indicate the Ni(NIXANTPHOS)-based catalyst exhibits enhanced reactivity over XANTPHOS derivatives and other Ni(phosphine)-based catalysts in the reactions examined.
