Check Digit Verification of cas no

The CAS Registry Mumber 1202-38-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,2,0 and 2 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1202-38:
(6*1)+(5*2)+(4*0)+(3*2)+(2*3)+(1*8)=36
36 % 10 = 6
So 1202-38-6 is a valid CAS Registry Number.

Cyclialkylation of arylalkyl epoxides with solid acid catalysts

Elings, Jacob A.,Downing, Roger S.,Sheldon, Roger A.

, p. 837 - 846 (2007/10/03)

Solid acids, such as zeolites and clays, catalyse the intramolecular hydroxyalkylation (cyclialkylation) of several arylalkyl epoxides in moderate to excellent conversions and selectivities. The use of solid acids in these cyclialkylations provides a cleaner, better alternative to conventional Lewis and Bronsted acids, enabling a more facile workup of reaction mixtures and, in several cases, better selectivities.
