Check Digit Verification of cas no

The CAS Registry Mumber 1443005-29-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,0,0 and 5 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1443005-29:
(9*1)+(8*4)+(7*4)+(6*3)+(5*0)+(4*0)+(3*5)+(2*2)+(1*9)=115
115 % 10 = 5
So 1443005-29-5 is a valid CAS Registry Number.

Pd-Catalyzed Indolization/peri-C–H Annulation/N-Dealkylation Cascade to Cyclopenta-Fused Acenaphtho[1,2-b]indole Scaffold

Jin, Tienan,Suzuki, Shin,Ho, Hon Eong,Matsuyama, Hidenori,Kawata, Masaki,Terada, Masahiro

supporting information, p. 9431 - 9435 (2021/12/14)

A novel Pd-catalyzed cascade reaction of N,N-dialkyl-substituted o-alkynylanilines involving an indolization/peri-C–H annulation/N-dealkylation sequence has been developed to construct a cyclopenta-fused acenaphtho[1,2-b]indole (ANI) scaffold. A variety of aromatic hydrocarbons having a peri-C–H bond at the alkynyl terminus, such as naphthalene, phenanthrene, pyrene, and fluoranthene, were employed, affording the corresponding π-extended ANI derivatives. The ANI molecules showed relatively narrow energy gaps by increasing HOMOs and lowering LUMOs, implying their potential applications as π-segments in low-band-gap materials.
