Check Digit Verification of cas no

The CAS Registry Mumber 1571142-45-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,7,1,1,4 and 2 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1571142-45:
(9*1)+(8*5)+(7*7)+(6*1)+(5*1)+(4*4)+(3*2)+(2*4)+(1*5)=144
144 % 10 = 4
So 1571142-45-4 is a valid CAS Registry Number.

Controllable access to multi-substituted imidazoles: Via palladium(II)-catalyzed C-C coupling and C-N condensation cascade reactions

Yu, Haihua,Xiao, Li,Yang, Xicheng,Shao, Liming

supporting information, p. 9745 - 9748 (2017/09/07)

A novel and efficient protocol for the synthesis of various 2,4-disubstituted, 1,2,4-trisubstituted and 1,2,4,5-tetra-substituted imidazoles via cascade palladium catalyzed C-C coupling followed by intramolecular C-N bond formation was developed. Readily accessible boronic acids and N-substituted-2-aminoacetonitriles were firstly reported as starting materials to construct di-, tri-, and tetra-substituted imidazoles in good to excellent yield.
