Check Digit Verification of cas no

The CAS Registry Mumber 1569261-64-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,9,2,6 and 1 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1569261-64:
(9*1)+(8*5)+(7*6)+(6*9)+(5*2)+(4*6)+(3*1)+(2*6)+(1*4)=198
198 % 10 = 8
So 1569261-64-8 is a valid CAS Registry Number.

Conversion of oxiranes and CO2 to organic cyclic carbonates using a recyclable, bifunctional polystyrene-supported organocatalyst

Whiteoak, Christopher J.,Henseler, Andrea H.,Ayats, Carles,Kleij, Arjan W.,Pericas, Miquel A.

, p. 1552 - 1559 (2014)

The development of a heterogeneous one-component bifunctional catalyst system able to catalyse the conversion of carbon dioxide and oxiranes to organic cyclic carbonates at low temperature (45 °C) is reported. The bifunctional system can be easily recycled and reactivated when required. When compared with other heterogeneous organocatalysts for the same transformation, the reported catalyst is active at much milder temperatures, thus emphasising the optimal sustainability profile of the new catalyst system.
