Check Digit Verification of cas no

The CAS Registry Mumber 90665-76-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,6,6 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 90665-76:
(7*9)+(6*0)+(5*6)+(4*6)+(3*5)+(2*7)+(1*6)=152
152 % 10 = 2
So 90665-76-2 is a valid CAS Registry Number.

THERMAL AND PHOTOCHEMICAL STUDIES WITH STILBENE OXIDES INTRAMOLECULAR TRAPPING OF CARBONYL YLIDE INTERMEDIATES

Brokatzky-Geiger, Juergen,Eberbach, Wolfgang

, p. 1137 - 1140 (2007/10/02)

The annelated tetrahydrofuran derivatives 14 and 15, resp., are formed in moderated yield by intramolecular trapping reaction of the carbonyl ylide intermediates 9, which are generated either by thermal ring opening of the trans-stilbene oxides 7t/8t or by photolysis of the cis-isomers 7c/8c.
