870672-07-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 870672-07-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,6,7 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 870672-07:
(8*8)+(7*7)+(6*0)+(5*6)+(4*7)+(3*2)+(2*0)+(1*7)=184
184 % 10 = 4
So 870672-07-4 is a valid CAS Registry Number.

Palladium-catalyzed atroposelective coupling-cyclization of 2-isocyanobenzamides to construct axially chiral 2-aryl- And 2,3-diarylquinazolinones

, p. 2722 - 2728 (2021/03/01)

A palladium-catalyzed imidoylative cycloamidation of N-alkyl-2-isocyanobenzamides with 2,6-disubstituted aryl iodides, affording unprecedented axially chiral 2-arylquinazolinones, has been developed with good yields and atroposelectivities. In this coupling-cyclization process, the biaryl linkage and the heteroaromatic ring are formed sequentially in one step. When N-(2,4dimethoxyphenyl)-2-isocyanobenzamide is applied as a substrate, 2,3-diarylquinazolinones containing two stereogenic axes are produced with moderate diastereoselectivity and good enantioselectivities.
