Check Digit Verification of cas no

The CAS Registry Mumber 261713-89-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,7,1 and 3 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 261713-89:
(8*2)+(7*6)+(6*1)+(5*7)+(4*1)+(3*3)+(2*8)+(1*9)=137
137 % 10 = 7
So 261713-89-7 is a valid CAS Registry Number.

The synthesis of a novel strained diyneparacyclophane and its dimer by metal-mediated coupling

Collins, Shawn K.,Yap, Glenn P.A.,Fallis, Alex G.

, p. 385 - 388 (2000)

Relieve strain with a twist! Synthesis of the paracyclophane 1 and its dimer 2 employed a sequence of metal-mediated couplings. The X-ray analysis of 2 revealed a helical twist inherent in this structure, which created extended arms, that trapped a molecule of solvent. A carboxylic acid derivative of 1 was also prepared, and its structure indicated the diyne rod moiety of 1 is distorted more than in analogous compounds.
