Check Digit Verification of cas no
The CAS Registry Mumber 35980-18-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,9,8 and 0 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 35980-18:
(7*3)+(6*5)+(5*9)+(4*8)+(3*0)+(2*1)+(1*8)=138
138 % 10 = 8
So 35980-18-8 is a valid CAS Registry Number.

A polystyrene-cross-linking bisphosphine ligand PS-DPPBz was used for Ni-catalyzed cross-coupling with organolithiums. A bench-stable precatalyst [NiCl2(PS-DPPBz)] enabled efficient coupling reactions between aryl chlorides and alkyllithiums. The heterogeneous Ni system showed good reusability. (Figure presented.).
