Check Digit Verification of cas no

The CAS Registry Mumber 1049822-91-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,4,9,8,2 and 2 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1049822-91:
(9*1)+(8*0)+(7*4)+(6*9)+(5*8)+(4*2)+(3*2)+(2*9)+(1*1)=164
164 % 10 = 4
So 1049822-91-4 is a valid CAS Registry Number.

Conformation as a protecting group: A regioselective aromatic bromination en route to complex π-electron systems

Guthrie, Daryl A.,Tovar, John D.

supporting information; experimental part, p. 4323 - 4326 (2009/06/06)

(Chemical Equation Presented) A new strategy to achieve regioselective functionalization of a sterically congested aromatic system driven by conformational demands is described. Electrophilic substitution occurs at the more planarizable subunit without undesired chemistry at mutually reactive sites and without the need for protecting or masking groups that must be manipulated later. Model studies are described to understand this selectivity, and possibilities for the construction of orthogonal, differentially substituted π-systems of relevance for molecular electronics are demonstrated.
