Check Digit Verification of cas no
The CAS Registry Mumber 289038-17-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,0,3 and 8 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 289038-17:
(8*2)+(7*8)+(6*9)+(5*0)+(4*3)+(3*8)+(2*1)+(1*7)=171
171 % 10 = 1
So 289038-17-1 is a valid CAS Registry Number.

A practical and general iron-catalyzed domino decarboxylation-oxidation of α,β-unsaturated carboxylic acids enabling aldehyde C-H methylation for the synthesis of methyl ketones has been developed. This mild, operationally simple method uses ambient air as the sole oxidant and tolerates sensitive functional groups for the late-stage functionalization of complex natural-product-derived and polyfunctionalized molecules.
1,4-Palladium Shift/C(sp3)-H Activation Strategy for the Remote Construction of Five-Membered Rings

1,n-Metal shift is an elegant alternative approach enabling the functionalization of remote C-H bonds from simple precursors. In this work, we report a novel and simple Pd0-catalyzed domino reaction involving 1,4-palladium shift and C(sp3)-H activation and leading to (fused) five-membered rings. This method allowed access to a broad range of valuable arylidene γ-lactams and indanones and was applied to the formal synthesis of (-)-pyrrolam.
