Check Digit Verification of cas no

The CAS Registry Mumber 499154-42-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,9,1,5 and 4 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 499154-42:
(8*4)+(7*9)+(6*9)+(5*1)+(4*5)+(3*4)+(2*4)+(1*2)=196

Solid-state diphotocyclization of iso- and terephthalaldehydes via dihalogen substitution

Moorthy, J. Narasimha,Venkatakrishnan,Mal, Prasenjit,Venugopalan

, p. 327 - 330 (2007/10/03)

The supramolecular nonbonded C-H···X interactions between formyl hydrogens and ortho-halogen atoms (Br/Cl) have been exploited to achieve conformational control in the solid state of dimethyl-substituted iso- and terephthaladehydes (1-3) for unprecedented
