901127-47-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 901127-47-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,1,1,2 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 901127-47:
(8*9)+(7*0)+(6*1)+(5*1)+(4*2)+(3*7)+(2*4)+(1*7)=127
127 % 10 = 7
So 901127-47-7 is a valid CAS Registry Number.

Helical chirality induction of expanded porphyrin analogues
Setsune, Jun-Ichiro
, p. 1151 - 1163 (2013/05/22)
Expanded porphyrin analogues with unique figure-eight conformation were prepared by way of useful pyrrole intermediates such as bis(azafulvene)s and 2-borylpyrrole. Supramolecular chirogenesis of cyclooctapyrrole O1 with 32π-cycloconjugation was successfu
