Check Digit Verification of cas no

The CAS Registry Mumber 63661-79-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,6,6 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 63661-79:
(7*6)+(6*3)+(5*6)+(4*6)+(3*1)+(2*7)+(1*9)=140
140 % 10 = 0
So 63661-79-0 is a valid CAS Registry Number.

A Simple Total Synthesis of Viburtinal

Brayer, Jean-Louis,Alazard, Jean-Pierre,Thal, Claude

, p. 257 - 258 (1983)

Viburtinal (2) has been synthesised from 2-cyclopentadienylpropanol (3) via the dihydrocyclopentapyran (1c), which was itself prepared via regioselective formylation.
