Check Digit Verification of cas no

The CAS Registry Mumber 1649451-33-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,4,9,4,5 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1649451-33:
(9*1)+(8*6)+(7*4)+(6*9)+(5*4)+(4*5)+(3*1)+(2*3)+(1*3)=191
191 % 10 = 1
So 1649451-33-1 is a valid CAS Registry Number.

Synthesis and characterization of geminally dialkylsubstituted tetraindanotetraoxa[8]circulenes

Mejlsoe, Soren L.,Christensen, Jorn B.

, p. 1051 - 1057 (2014)

A synthetic methodology for the synthesis of 2,2-dialkyl-4,7-dimethoxy-2,3- dihydro-1H-inden-1-ones from 4,7-dimethoxy-2,3-dihydro-1H-inden-1-one has been developed, and some of these compounds were converted into the corresponding geminally dialkylsubstituted tetraindanotetraoxa[8]circulenes with the expectation of obtaining discotic liquid crystalline materials.
