Check Digit Verification of cas no

The CAS Registry Mumber 81981-25-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,9,8 and 1 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81981-25:
(7*8)+(6*1)+(5*9)+(4*8)+(3*1)+(2*2)+(1*5)=151
151 % 10 = 1
So 81981-25-1 is a valid CAS Registry Number.

The Reactions of Furfuryl Alcohols with Maleic Anhydride

Pelter, Andrew,Singaram, Bakthan

, p. 1383 - 1386 (2007/10/02)

The reactions of furfuryl alcohols (1a) and (1b) with maleic anhydride were investigated and, for the first time, conditions defined for the production of intramolecular Diels-Alder adducts.Under basic conditions the adducts (3a,b) yield phthalides in high yield.Furfuryl alcohols (1c) and (8a) afford normal intermolecular Diels-Alder adducts with maleic anhydride.
