Check Digit Verification of cas no

The CAS Registry Mumber 104788-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,8 and 8 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 104788-48:
(8*1)+(7*0)+(6*4)+(5*7)+(4*8)+(3*8)+(2*4)+(1*8)=139
139 % 10 = 9
So 104788-48-9 is a valid CAS Registry Number.

MECHANISTIC RATIONALIZATION OF AN APPARENTLY NON-STEREOSPECIFIC INTRAMOLECULAR DIELS-ALDER REACTION.

Magnus, Philip,Walker, Clive,Jenkins, Paul R.,Menear, Keith A.

, p. 651 - 654 (1986)

The loss of dienophile stereochemistry in the conversion of 1/4 into 1/6 is shown to result from epimerization α- to the lactone carbonyl via 9.
