Check Digit Verification of cas no

The CAS Registry Mumber 105399-03-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,3,9 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 105399-03:
(8*1)+(7*0)+(6*5)+(5*3)+(4*9)+(3*9)+(2*0)+(1*3)=119
119 % 10 = 9
So 105399-03-9 is a valid CAS Registry Number.

PREPARATION AND STRUCTURE OF AN UNUSUAL DIMERIC FURAN FROM THE ACID DECOMPOSITION OF ISOMALTOL

Goodwin, James C.,Hodge, John E.,Weisleder, David

, p. 107 - 112 (1986)

Isomaltol (1), an enolic nonenzymic browning-product, decomposes in dilute acid to form the new red-orange colored, symmetrical dimer, (E)-2--(2H)-furan-3-one (2).Compound 2 was obtained in 20.4percent yield with toluenesulfonic acid (>/=3M) at 50 deg C.The structure for 2 was assigned on the basis of spectral data (m.s., u.v., i.r., 13C- and 1H-n.m.r.) and conversion into its mono-O-acetyl derivative (3).
