Check Digit Verification of cas no

The CAS Registry Mumber 127604-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,6,0 and 4 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 127604-89:
(8*1)+(7*2)+(6*7)+(5*6)+(4*0)+(3*4)+(2*8)+(1*9)=131
131 % 10 = 1
So 127604-89-1 is a valid CAS Registry Number.

E- and Z- isomers of spirocyclic 5-arylmethylene-1,3-dioxane-4,6-dione, useful synthons for enantiomerically pure cyclopropane-1,1-dicarboxylates, have been synthesized from 1-menthone.Their diastereofacial selectivity is explained by a boat conformation in their dioxanedione ring.
