Check Digit Verification of cas no

The CAS Registry Mumber 1240504-02-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,5,0 and 4 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1240504-02:
(9*1)+(8*2)+(7*4)+(6*0)+(5*5)+(4*0)+(3*4)+(2*0)+(1*2)=92
92 % 10 = 2
So 1240504-02-2 is a valid CAS Registry Number.

Buchwald ligand-assisted Suzuki cross-coupling of polychlorobenzenes

Burukin, Alexander S.,Vasil'ev, Andrei A.,Zhdankina, Galina M.,Zlotin, Sergei G.

, p. 400 - 402 (2021)

Screening of four Buchwald ligands for the cross-coupling of isomeric di-, tri- and tetrachlorobenzenes with arylboronic acids revealed that good yields of exhaustive substitution can be best provided by 2-dicyclohexylphosphino-2′-(dimethylamino) biphenyl (DavePHOS).
