Check Digit Verification of cas no

The CAS Registry Mumber 1219623-22-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,9,6,2 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1219623-22:
(9*1)+(8*2)+(7*1)+(6*9)+(5*6)+(4*2)+(3*3)+(2*2)+(1*2)=139
139 % 10 = 9
So 1219623-22-9 is a valid CAS Registry Number.

Total synthesis confirms laetirobin as a formal diels-alder adduct

Simon, Oliver,Reux, Bastien,La Clair, James J.,Lear, Martin J.

experimental part, p. 342 - 351 (2010/07/13)

Laetirobin, isolated from a parasitic fungus host-plant relationship, was synthesized in six practical steps with an overall yield of 12% from commercially available 2,4-dihydroxyacetophenone. Because the product is a pseudosymmetric tetramer of benzo[b]-
