Check Digit Verification of cas no

The CAS Registry Mumber 139670-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,7 and 0 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139670-44:
(8*1)+(7*3)+(6*9)+(5*6)+(4*7)+(3*0)+(2*4)+(1*4)=153
153 % 10 = 3
So 139670-44-3 is a valid CAS Registry Number.

LONG-RANGE EXCITON COUPLING FROM DIPYRRINONE CHROMOPHORES

Byun, Young-Seok,Lightner, D. A.

, p. 9759 - 9772 (1991)

Dipyrrinone chromophores, attached by their acid termini to give (1R,2R)-cyclohexanediol dipropionate and diacetate esters (xanthobilirubinate and nor-xanthobilirubinate, respectively), interact through exciton coupling, as evidenced by intense bisignate
