Check Digit Verification of cas no

The CAS Registry Mumber 1301219-73-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,0,1,2,1 and 9 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1301219-73:
(9*1)+(8*3)+(7*0)+(6*1)+(5*2)+(4*1)+(3*9)+(2*7)+(1*3)=97
97 % 10 = 7
So 1301219-73-7 is a valid CAS Registry Number.

scheme or table, p. 2360 - 2365 (2011/06/16)

Synthesis of carbazol-4-ones, 3,4-dihydrocyclopental-indol-1-one, and indole derivatives by a Fe/AcOH-mediated intramolecular reductive N-heteroannulation of 3-hydroxy-2-(2-nitrophenyl)enones is demonstrated. The same protocol has been extended to access indolocarbazolone and indoloquinolone derivatives. Synthesis ofderivatives by a Fe/AcOH-mediated intramolecular reductive N-heteroannulation strategy is demonstrated. The starting materials were easily accessed from C-arylation of 1,3-diketones by o-nitroiodobenzenes. Copyright
