Check Digit Verification of cas no

The CAS Registry Mumber 1356542-31-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,6,5,4 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1356542-31:
(9*1)+(8*3)+(7*5)+(6*6)+(5*5)+(4*4)+(3*2)+(2*3)+(1*1)=158
158 % 10 = 8
So 1356542-31-8 is a valid CAS Registry Number.

Synthesis of annulated pyridines by intramolecular inverse-electron-demand hetero-diels-alder reaction under superheated continuous flow conditions

Martin, Rainer E.,Morawitz, Falk,Kuratli, Christoph,Alker, Andre M.,Alanine, Alexander I.

supporting information; experimental part, p. 47 - 52 (2012/01/14)

Pyrimidine alkynes can be transformed into the corresponding annulated pyridines efficiently in flow. The superheating of organic solvents far beyond their boiling point enables toxic and difficult to workup solvents such as nitrobenzene or chlorobenzene,
