Check Digit Verification of cas no

The CAS Registry Mumber 112518-92-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,5,1 and 8 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 112518-92:
(8*1)+(7*1)+(6*2)+(5*5)+(4*1)+(3*8)+(2*9)+(1*2)=100
100 % 10 = 0
So 112518-92-0 is a valid CAS Registry Number.

Novel Two-Step Synthesis of Homobarrelenones, Bicyclonona-3,6,8-trien-2-ones, from Tropones and 2,3-Bis(methoxycarbonyl)-7-oxabicyclohepta-diene by High-Pressure Cycloaddition-Thermal Cyclorevision Procedure

, p. 1557 - 1560 (2007/10/02)

The Diels-Alder adduct of tropone with 2,3-bis(methoxycarbonyl)-7-oxabicyclohepta-2,5-diene formed homobarrelenone by heating at ca. 130 deg C.Similarly prepared were 1-hydroxy-, 3-methoxy-, 1-chloro-, and 3-chlorohomobarrelenones.High-pressure cycloaddition improved the yields of the Diels-Alder adducts.
