The CAS Registry Mumber 139256-87-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,5 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 139256-87:
(8*1)+(7*3)+(6*9)+(5*2)+(4*5)+(3*6)+(2*8)+(1*7)=154
154 % 10 = 4
So 139256-87-4 is a valid CAS Registry Number.

PHOTOLYSIS OF 2-PIPERIDINO- AND 2-MORPHOLINO-3-METHOXY-1,4-NAPHTHOQUINONES

Shishkina, R. P.,Berezhnaya, V. N.,Mamatyuk, V. I.

, p. 624 - 627 (1991)

PMR and 13C NMR spectroscopy was used to establish the structure of the primary products of the photolysis of 2-piperidino- and 2-morpholino-3-methoxy-1,4-naphthoquinones.A scheme for the subsequent dark transformations of these compounds is proposed.
