Check Digit Verification of cas no

The CAS Registry Mumber 152904-73-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,2,9,0 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 152904-73:
(8*1)+(7*5)+(6*2)+(5*9)+(4*0)+(3*4)+(2*7)+(1*3)=129
129 % 10 = 9
So 152904-73-9 is a valid CAS Registry Number.

, p. 2707 - 2713 (2007/10/02)

The syntheses of a novel diphenyl-substituted thiophene, pyrrole, and furan fused at the 3- and 4-positions with norbornadiene are described.Structures of these molecules are discussed on the basis of spectral properties by comparison with those of cycloh
