Check Digit Verification of cas no

The CAS Registry Mumber 1224595-40-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,2,4,5,9 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1224595-40:
(9*1)+(8*2)+(7*2)+(6*4)+(5*5)+(4*9)+(3*5)+(2*4)+(1*0)=147
147 % 10 = 7
So 1224595-40-7 is a valid CAS Registry Number.

Pd-PEPPSI-IPent: Low-temperature negishi cross-coupling for the preparation of highly functionalized, tetra-ortho-substituted biaryls

Calimsiz, Selcuk,Sayah, Mahmoud,Mallik, Debasis,Organ, Michael G.

supporting information; experimental part, p. 2014 - 2017 (2010/06/20)

(Chemical Equation Presented) Cool couplings: Complex, hindered biaryls have been prepared at temperatures ranging from 0°C to room temperature, or with gentle heating. The Pd-PEPPSI-IPent catalyst (see scheme) nicely couples starting materials containing acidic moieties and routinely prepares biaryl derivatives where one or both rings comprising the biaryl are heterocyclic. Ar1=hindered aryl or heteroaryl, Ar2=unactivated aryl or heteroaryl.
