Check Digit Verification of cas no

The CAS Registry Mumber 127099-70-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,9 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127099-70:
(8*1)+(7*2)+(6*7)+(5*0)+(4*9)+(3*9)+(2*7)+(1*0)=141
141 % 10 = 1
So 127099-70-1 is a valid CAS Registry Number.

Cu/Picolinamides-Catalyzed Coupling of (Hetero)aryl Halides with Secondary Phosphine Oxides and Phosphite?

Fang, Chao,Wei, Bangguo,Ma, Dawei

, p. 2957 - 2961 (2021)

Some 4-hydroxy-picolinic acid derived amides were revealed as more efficient ligands for Cu-catalyzed coupling of (hetero)aryl halides with secondary phosphine oxides and phosphites. Only 3—5 mol% CuI and ligands were required to ensure coupling with a number of (hetero)aryl bromides and iodides to complete at 120 oC in 10—20 h.
