Check Digit Verification of cas no

The CAS Registry Mumber 1267640-07-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,7,6,4 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1267640-07:
(9*1)+(8*2)+(7*6)+(6*7)+(5*6)+(4*4)+(3*0)+(2*0)+(1*7)=162
162 % 10 = 2
So 1267640-07-2 is a valid CAS Registry Number.

Strained cyclophane macrocycles: Impact of progressive ring size reduction on synthesis and structure

Bogdan, Andrew R.,Jerome, Steven V.,Houk,James, Keith

supporting information; experimental part, p. 2127 - 2138 (2012/03/10)

The synthesis, X-ray crystal structures, and calculated strain energies are reported for a homologous series of 11- to 14-membered drug-like cyclophane macrocycles, representing an unusual region of chemical space that can be difficult to access synthetic

Efficient access to new chemical space through flow-construction of druglike macrocycles through copper-surface-catalyzed azide-alkyne cycloaddition reactions

Bogdan, Andrew R.,James, Keith

supporting information; experimental part, p. 14506 - 14512 (2011/03/20)

A series of 12- to 22-membered macrocycles, with druglike functionality and properties, have been generated by using a simple and efficient copper-catalyzed azide-acetylene cycloaddition reaction, conducted in flow in high-temperature copper tubing, under
