Check Digit Verification of cas no

The CAS Registry Mumber 1217269-85-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,7,2,6 and 9 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1217269-85:
(9*1)+(8*2)+(7*1)+(6*7)+(5*2)+(4*6)+(3*9)+(2*8)+(1*5)=156
156 % 10 = 6
So 1217269-85-6 is a valid CAS Registry Number.

For the last ten years, ring-shaped π-conjugated macrocycles possessing radially directed π-orbitals have been subject to intense research. The electronic properties of these rings are deeply dependent on their size. However, most studies involve the flag

Selective and gram-scale synthesis of [8]cycloparaphenylene

Ishida, Kosuke,Kawanishi, Tatsuya,Kayahara, Eiichi,Yamago, Shigeru

, p. 2082 - 2091 (2020/03/11)

Selective and large-scale synthesis of [8]cycloparaphenylene (CPP) was achieved in seven steps starting from commercially available 4-bromo-4′-hydroxybiphenyl and 4,4′-dibromobiphenyl. The key unsymmetrical tetraring unit, 4-bromophenyl and 4′-bromobiphenyl-substituted cis-1,4-bis(triethylsiloxy)-2,5-cyclohexadiene-1,4-diyl (5fA), was synthesized on an ~50 g scale by stereoselective cis-addition of 4-bromo-4′-lithiobiphenyl to 4-(4-bromophenyl)-4-hydroxy-2,5-cyclohexadien-1-one, which was synthesized on an ~100 g scale. Platinum-mediated selective dimerization of the four-ring unit 5fB and subsequent reductive aromatization of the cyclohexadiene-diyl by H2SnCl4 gave 2 g of [8]CPP in 6.6% overall yield (10.2% on small scale).
