Check Digit Verification of cas no

The CAS Registry Mumber 1218769-20-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,1,8,7,6 and 9 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1218769-20:
(9*1)+(8*2)+(7*1)+(6*8)+(5*7)+(4*6)+(3*9)+(2*2)+(1*0)=170
170 % 10 = 0
So 1218769-20-0 is a valid CAS Registry Number.

Synthesis of quinoxaline quinones and regioselectivity in their Diels-Alder cycloadditions

Sharma, Gitanjali,Raisinghani, Pankaj,Abraham, Ignatious,Pardasani,Mukherjee, Tulsi

experimental part, p. 1590 - 1596 (2010/03/25)

A facile synthesis of quinoxaline quinones is reported. The regioseleclivily in their Dicls-Alder cycloaddition reactions has been investigated at AM I level using Gaussian 98 and MOPAC 6 programs. The products have been characterized from their spectral
