Check Digit Verification of cas no

The CAS Registry Mumber 640284-29-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,0,2,8 and 4 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 640284-29:
(8*6)+(7*4)+(6*0)+(5*2)+(4*8)+(3*4)+(2*2)+(1*9)=143
143 % 10 = 3
So 640284-29-3 is a valid CAS Registry Number.

The Chemistry of 1,6-Dioxapyrenes Part 3 [1,2]: Scope and Limitations of an Acid Catalyzed Ring-closing Reaction

Christensen, Jorn B.,Bechgaard, Klaus

, p. 757 - 761 (2003)

One of the few methods for synthesis of 1,6-dioxapyrenes is the acid catalyzed cyclization of 2,6-disubstituted 1,5-bis(2-oxoalkoxy)naphthalenes. The scope and limitations of this reaction has been investigated and 11 new 2,7-disubstituted 1,6-dioxapyrene
