Check Digit Verification of cas no

The CAS Registry Mumber 1041445-67-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,1,4,4 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1041445-67:
(9*1)+(8*0)+(7*4)+(6*1)+(5*4)+(4*4)+(3*5)+(2*6)+(1*7)=113
113 % 10 = 3
So 1041445-67-3 is a valid CAS Registry Number.

One-pot synthesis of cyclic triamides with a triangular cavity from trans-stilbene and diphenylacetylene monomers

supporting information; experimental part, p. 3207 - 3210 (2009/05/11)

(Chemical Equation Presented) Base-promoted self-condensation reactions of trans-stilbene and diphenylacetylene monomers bearing 4-alkylamino and 4′-methoxycarbonyl groups were investigated. Reactions of N-propyl monomers under pseudohigh-dilution conditions (a THF solution of monomer was added dropwise to a THF solution of LiHMDS) afforded the corresponding cyclic triamides in good yields. X-ray crystallographic analysis showed that these cyclic triamides possessed an almost equilateral triangle structure with a cavity surrounded by tilted benzene rings.
