Check Digit Verification of cas no

The CAS Registry Mumber 158670-19-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,6,7 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 158670-19:
(8*1)+(7*5)+(6*8)+(5*6)+(4*7)+(3*0)+(2*1)+(1*9)=160
160 % 10 = 0
So 158670-19-0 is a valid CAS Registry Number.

Palladium-catalyzed C-3 desulfitative arylation of indolizines with sodium arylsulfinates and arylsulfonyl hydrazides

Wang, Chunjie,Jia, Huali,Li, Zhiwei,Zhang, Hui,Zhao, Baoli

, p. 21814 - 21821 (2016/03/08)

Derivatized indolizines were efficiently prepared by direct C-3 arylation of indolizines using sodium arylsulfinates and arylsulfonyl hydrazides. Pd-catalyzed desulfitative C-3 arylation with sodium arylsulfinates was achieved with the assistance of peroxides, and the catalytic efficiency was promoted by N-containing ligands. Arylsulfonyl hydrazides were also successfully applied in Pd-catalyzed desulfitative C-3 arylation with indolizines, and the side homocoupling reactions can be restrained in the component solvent under milder conditions. Various derivatives were synthesized in good yields by both methods, offering expedient protocols for the synthesis of C-3 functionalized indolizine molecules.
